Defence of generating units and power systems against system disturbance of the black-out type

The National power system connected to other European countries power systems provides electric power supply of high reliability. However as the last system breakdowns have shown it is not 100% reliable. Loss of power supply by customers as well as connection to the network by generating units may constitute a serious hazard for them.

Our specialists for many years have been participating in projects aimed at protection of power systems in power plants, heat and power generating plants and industrial plants with their own generating units in the event of a system disturbance of the black-out type. The activities connected with the above mentioned problem can be divided into four stages:

  • in the first stage a detailed analysis of the power system and the devices supplied by this system is carried out in order to assess the possibility of island operation of the system, without connection to the National power system, and search for weak points that determine the possibility of island operation;
  • in the second stage remedies are drawn up (technical and organizational) that should be implemented in order to eliminate the system weak points and to adapt the power system to operation without connection to National power system;
  • the third stage concerns participation in the execution of tasks worked out in the second stage;
  • in the fourth stage the tests are carried out on the site with a view to confirming the possibility of island operation of the power system and to conduct an essential training of the operating staff; the results of the tests constitute the ground for drawing essential manuals up

The team also organizes and carries out acceptance tests, periodic verifying tests and system trials according to the requirements of the Instruction of Transmission System Operation and Maintenance (PSE-Operator S.A.) the aim of which is to verify the ability 
of generating unit to participate in the process of defense and restoration of the National power system.

Measurements of partial discharge with electric method

Electromagnetic Field and Partial Discharge Division performs measurements of partial discharge (wnz) with electric off-line method. This valuable form of diagnostics of the state of insulation finds application in the case of many diverse electrical power engineering devices. Its aim is to detect defects arising from technological and operational reasons poorly detectable with other methods, but significant for durability of the object The partial discharge is a local electrical discharge which takes place only in part of the electro-insulating system and doesn't cause direct loss of insulating properties by the object. However long-term occurrence of partial discharge often leads to such changes in the structure of insulation that cause the disruptive discharge (breakdown). Partial discharge occurs in structures of insulation systems of practically all high voltage electric equipment of the high voltage, that is for example:

  • stators and rotors of generators,
  • oil-immersed and dry-type transformers,
  • current and voltage transformers,
  • power capacitors,
  • high voltage switchgears.

Testing of the energy quality

The scope of tests encompasses all quantities being characteristic of quality of the energy detailed at the up-to-date regulations, such as:

  • level, frequency and changes of supply voltage root-mean-square value,
  • voltage and current higher harmonics contents (determining of voltage and current distortion factor),
  • voltage asymmetry (in three-phase systems),
  • energy supply interruptions,
  • quick-variable changes of supply voltage (voltage dips and flares),
  • light flickering noxiousness (due to voltage fluctuations, so-called flicker effect), that is subjective impression of the change of illuminance.

Moreover, we offer:

  • monitoring of the active and reactive power consumption as well as the power flow in any time intervals,
  • technical consulting on establishing the terms of power supply,
  • selection, installation, start-up and check measurements of the equipment for the reactive power compensation,
  • selection of equipment to ensure the correct operation of energy receivers.

The measurements that are the basis for energy quality analysis, are carried out with the recording equipment with up-to-date verification certificates. The results of our works can serve as credible evidence in controversial issues on the line supplier – consumer of the energy. In view of the necessity of permanent control of energy quality, we offer our customers systems realized in our company for continuous monitoring of the power network parameters. The systems allow measurement of electric power quality at the selected points of the power network as well as transmission of data to the central computer. Power quality monitoring system consists of distributed Power Network Analysers (AS). Every AS is an independent measuring point. The AS internal memory allows to record and review the selected parameters and events.RS485/232 interfaces and Modbus protocol is used for communication between analysers. Depending on the noise and distance, the transmission paths can be of fibre-optic, electric twisted-pair cable or wireless systems (GPS, radio link). All over one GPZ (Main Supply Point) can operate simultaneously up to 64 AS. The individual AS, apart from energy quality parameters, measures and records the following power network parameters:

  • V, I, KW, KVR, KVA, cos, tg, Ekv, Ekvr, Ekva
  • real-time diagrams of current and voltage (storage oscilloscope).

Power network parameters' quality monitoring system provides:

  • communication with Power Network Analysers (AS),
  • on-line visualization of quantities measured,
  • alarm signalization on exceed the thresholds and limits,
  • archiving and off-line browsing of quantities measured,
  • web access to the quantities measured,
  • processing of quantities measured,
  • recording to a file / printing the archived data,
  • co-operation with other systems operated in power industry.

We guarantee a liable and diligent realization of works ordered.

Computer system for visual presentation and registration of synchronization process criteria quantities and power system switching

Computer system for visual presentation and registration of synchronization process criteria quantities and power system switching

The system presented here is a result of our long-term experience in the scope of registration and analysis of electric processes and it is an answer  to the growing demand of the market resulting from the necessity of executing international synchronization processes and switching of separated island systems to the NPS (National Power System) (e.g. power network of large industrial plants). The virtual measurement environment has been organized that, from the user point of view, consists of conventional connected with one another instruments graphically presented on a computer screen.

The system is characterized by significant flexibility that cannot be achieved with conventional technology. On the basis of PSE-Operator S.A. decision the MUW system was adopted for applying in cross-border electricity exchange transformer stations and was installed in the following transformer stations: Mikułowa, Krajnik, Krosno-Iskrzynia, Mory and Wrocław heat and power plant. The system played the substantial role during tests of connection of UCPTE and CENTREL systems in October 1995. Starting next installations in transformer stations is planned e.g.: Bujaków, Wielopole.

MUW devices found application during the entire sequence of system trials in separating, creating and repeated synchronization of the island systems to the NPS (National Power System).  An example constitute the island operation tests carried out at the power plants: Połaniec (1995, 1996), Skawina (1996, 1997), Turów (1999, 2000, 2004).

The system is offered in the industrial workmanship based on modern elements of reputable producers. MUW provides all functions of traditional synchronizing units and introduces new functions impossible to obtain with old technologies. Metrological properties of the MUW device are particularly significant.

The fact that the system doesn't require applying any additional computer devices is worth of stressing.

MUW system enables:

  • observation in the real time on the external industrial monitor of criteria parameters of switching processes (slipping, voltages difference, phase shift and the like),
  • registration of criteria parameters of switching processes,
  • assembly in the automatic system cabinet of 19" standard.

Experience gained from the previous operation of the MUW system showed that synchronization of large power systems and island systems carried out with the use of conventional technical methods was unusually difficult and to all intents and purposes impossible to realize. A possibility of registration and documenting the whole switching process is an additional advantage resulting from application of the MUW system. As an option the system can be equipped with the recorder of transient states (current surges, power swing, etc.) appearing in the moment of closing of circuit breaker.  High-tech solutions both in the equipment as well as the software were applied for the design of the proposed system. Visual presentation and registration system of the MUW can be consolidated with the wide range of automatic and semi-automatic synchronizers of domestic and foreign production. Our company can also undertake the realization of the complete synchronization system containing among other things the automatic switching system cabinet. The above works were successfully carried out by Energopomiar-Elektryka company at the majority of customers of the MUW system. During the 10th jubilee fair "The high technology for Power Industry" at Bielsko-Biała 1997 PSE-Operator S.A. granted our Computer disturbance registration system, control device state signalling system and switching processes visualisation system a gold medal.

Electrical parameters registration and analysis system SAS-PLUS

The presented system is a result of our more than 20 years of experience in the scope of registration and analysis of electrical quantities which is meant to meet the market needs connected with the necessity of performing sophisticated analysis of power network at large industry plants, in accordance with the domestic standards (e.g. determination of energy quality parameters acc. to the PN-EN 50160 standard).

A virtual measurement environment has been designed which, from the user's point of view, consists of conventional, interrelated between one another measuring instruments graphically presented on a computer screen. Moreover, its software has a great flexibility.

The system is offered in the industrial workmanship (industrial computers and measurement cards, real time operating systems, mechanics of 19" standard) based on modern elements of reputable producers.

The SAS-PLUS provides all functions of conventional measuring devices as well as introduces new functions which cannot be used with the old technology.

Particularly significant and distinguishing feature of the SAS-PLUS system are metrological properties guaranteeing measurements of above average accuracies and dynamics in the time domain. SAS-PLUS

The SAS-PLUS system has the metrological confirmation issued by the specialist measurement equipment laboratory accredited by the Polish Centre for Accreditation (PCA).

Measuring signals delivered to the system:

  • voltage from voltage transformers of the tested supervised system (UL1, UL2, UL3, U0),
  • currents from current transformers of the supervised system (IL1, IL2, IL3, I0),
  • binary signals.

SAS-PLUS system allows:

  • local (on the monitor connected) and remote (at the selected workstations operating in heterogeneous distributed computer network) measurement and visualization of the selected electrical parameters of the system tested (rms currents and voltages, harmonic content in currents and voltages, t.h.d. coefficients, active and reactive power, electric energy, frequency, phase shifts, voltage unbalance coefficients, power direction of flow, exceeding of assumed limits e.g. power, etc.). These tasks are being performed in the real time in order to determine the current and historical state of the supervised electric power systems,
  • local and remote registration of selected electrical parameters,
  • registration of disturbances (dynamic electrical transient states and quasi-steady states),
  • registration of events.

SAS-PLUS system cooperates among other things with Power System Protection. The system is characterized by high-tech solutions both in the equipment as well as the software. The device constitutes the element of the distributed heterogeneous measuring network of the real time.
System of the visualisation and the registration SAS-PLUS can be consolidated among other things with:

  • any class supervision system working under the computer operating system selected by the Customer: MS Windows, LINUX or UNIX using open network communication protocols for manufacturing application,
  • WWW browsers of the selected SAS-PLUS Customers,
  • telecommunication systems.

Experience gained at the current/previous operation of the SAS-PLUS system demonstrated that comprehensive analysis of large power networks performed with the use of conventional technical methods was unusually difficult and to all intents and purposes impossible to realize. A possibility of registration and documenting the whole process is an additional advantage resulting from application of the SAS-PLUS system. The system is equipped with the high class recorder of transient states (current surges, power swing, etc.) and event recorder.  ZPBE Energopomiar-Elektryka company can also undertake the realization of the complete system containing among other things the automatic switching system cabinet and computer-based telecommunication device.
