Network and System Testing Department
Our department specializes in providing advanced engineering services in the field of electrical power engineering. We focus primarily on technical analyses, supervision of assembly work, as well as research, testing, and commissioning of electrical systems – including power automation systems. We implement projects in both the commercial and industrial power sectors, ensuring the highest level of reliability and safety.
Scope of services:
- Compliance testing of generating units for the implementation of system defense plan and restoration plan procedures
- Support for connection procedures to the power system
- Operational, post-installation, modernization, and commissioning tests of power equipment
- Power protection tests
- Shock protection tests
- Power quality tests
- Measurements and calculations of electrical parameters of power lines
- Post-installation/periodic tests of MV and HV cable lines
- Conducting FAT and SAT
- Testing and repair of gas-flow relays
- SGU tests
Compliance tests with grid codes
- Preparation of detailed test and trial programs based on the requirements of the Grid Code and the requirements of the Grid Code regarding the connection of generating units to the NC RfG grid
- Preparation of detailed test and trial programs based on the requirements of the Grid Code and the requirements of the Grid Code regarding the state of emergency and the reconstruction of power systems NC ER
- Conducting complete compliance tests on-site according to agreed detailed programs
- Conducting autonomous start-up tests of power plants
- Conducting island operation tests of generating units
- Conducting system tests of starting a thermal power plant from a source capable of autonomous start-up
- Conducting system tests of connecting the National Power System with our neighbors' systems
We perform mandatory tests for power plants and the transmission grid operator, and repeat them periodically.
Supporting connection procedures
For newly connected power generating plants and distribution grid operators, we prepare:
- Technical analyses using simulation models,
- Operational cooperation instructions and energizing programs (for the EON application),
- Performance analyses and compliance simulations, detailed test programs and schedules (for the EON application) ION),
- All tests on facilities, including their assessment, and we prepare materials for the FON application.
For type B modules, we perform compliance simulations in the absence of certificates, facility-specific compliance tests, and prepare materials for the PGMD document.
Other measurements and tests
Measurements and calculations of electrical parameters of LV and HV power lines, including the measurement of:
- phase conductor resistance of line paths,
- impedance of line paths for symmetrical components,
- positive and negative,
- impedance of line paths for zero symmetrical components,
- susceptance of line paths for positive and negative components opposite,
- susceptance of line paths for the zero sequence.
- Testing and repair of gas-flow relays.
- Power quality tests.
