Grid Code Tests

Energopomiar is an expert company with high market recognition which performs comprehensive Grid Code Tests of power-generating modules in accordance with the requirements of:
- TSO (PSE SA) and distribution system operators set out in the Instruction of Transmission/Distribution System Operation and Maintenance (IRiESP/IRiESD)
- Commission Regulation (EU) 2016/631 of 14 April 2016 establishing a network code on requirements for grid connection of generators (NC RfG)
- Commission Regulation (EU) 2017/2196 of 24 November 2017 establishing a network code on electricity emergency and restoration (NC ER).
During the implementation of NC RfG requirements, our company participated in the work of the commission of the Polish Power Transmission and Distribution Association (PTPiREE) for the development of testing procedures and principles for power-generating modules.
Grid Code Tests are carried out for:
- new type C and type D power-generating modules connected to the transmission/distribution system subject to the requirements of NC RfG and NC ER
- existing power-generating modules (periodic and control tests) subject to the requirements of IRiESP, IRiESD and SGU Test Plan.
Due to the applied technology of energy generation and the method for grid connection of power-generating modules, Grid Code Tests are performed for:
- synchronous power-generating modules (conventional thermal power plants and hydropower plants)
- power park modules – PPM (wind farms, photovoltaic farms)
Energopomiar carries out the following tests to verify essential technical capabilities:
Grid Code Tests/compliance tests of type C and type D power-generating modules connected to the grid of the relevant System Operator
- LFSM-O
- LFSM-U
- FSM (primary control)
- frequency restoration control (secondary control)
- black start capability
- house load operation
- reactive power capability
- voltage control
- reactive power control
- power factor control
- power oscillation damping control (PSS)
- island operation
- minimum load capability
- maximum load capability
- active power control capability (tertiary control)
- AVR (Automatic Voltage Control) under load condition
- ARNE (Power Plant Automatic Voltage Control)
- start-up times
- runbacks and emergency complete shutdown.
Additional tests of newly connected power-generating modules
- operation in isolated/island systems test (separate checks for voltage and frequency control related to defense and restoration plan)
- black start capability test
- deadbus energizing test
- power system test of the thermal power plant starting-up by the PGM with black start capability.
Periodic tests of SGU (significant grid users) of existing power-generating modules
- operation in isolated/island systems test (separate checks for voltage and frequency control related to defense and restoration plan)
- black start capability test
- deadbus energizing test
- power system test of the thermal power plant starting-up by the PGM with black start capability.
Additional tests of newly connected power-generating modules
- simplified tests if there is no proper certificate of equipment/component (type B power-generating modules)
- preparation of the required attachments to EON, ION and FON applications (type D power-generating modules)
- performance guarantee tests in the scope of testing the measurement and visualization system and automatic control systems (ACS).
