KETOP provides testing services for grid-connected automation equipment, AGC control systems, AVC control systems, and new energy grid-integration performance across various types of power stations.
Applicable Product Types
Substations and converter stations at various voltage levels, thermal power stations, hydroelectric power stations, pumped storage power stations, photovoltaic power stations, wind power stations, and energy storage power stations.
New Energy Tests
■ Acceptance testing for electric vehicle charging and swapping stations, grid-connection acceptance for photovoltaic power stations, and grid-connection acceptance for energystorage power stations, etc.
■ Equipped with comprehensive new energy test instruments, featuring integrated functions such as real-time waveform recording, data analysis, and parameter testing. The system combines a frequency generator, data acquisition, recording, special condition capturing, long-term data logging, parameter calculation, performance analysis, graphic processing, table generation, and test result output, thereby meeting the testing requirements of grid integration for wind farms, photovoltaic stations, and energy storage stations.
Electromagnetic Compatibility (EMC) Tests
Capable of carrying out tests that meet on-site conditions, including electrostatic discharge(ESD) immunity, electrical fast transient (EFT) immunity, surge immunity, conducted RF immunity, and on-site electromagnetic environment measurements.
Acceptance testing of network-related automation devices
Equipped with multiple types of relay protection testers, time synchronization system testers, and network testers, enabling data acquisition, key function verification, and performance parameter checking of in-station network-related automation devices.
Acceptance testing of AGC/AVC（Automatic Generation Control / Automatic Voltage Control） control systems
Equipped with power analyzers and other devices, enabling functional verification, safety logic verification, consistency verification with dispatching protocols, and data consistency verification of in-station AGC control systems.
