Abstract

The invention discloses a unit primary frequency modulation online test substation system based on active test. The system comprises a primary frequency modulation test module, a data acquisition monitoring module, a primary frequency modulation assessment module, a wide-area phasor measurement module, a scheduling data network module, a telecontrol terminal, a primary frequency modulation test substation, a synchronous vector measurement module and a DCS module. Management and control over the primary frequency modulation function of the power plant unit can be enhanced, the primary frequency modulation performance level of the unit is improved, the frequency quality of a power grid is remarkably improved, comprehensive troubleshooting and analysis work of the primary frequency modulation function and performance of the generator unit in a region can be achieved, and reason classification and statistics are conducted on the unit with poor primary frequency modulation response; evaluation on the grid-related performance of each generator set on the power supply side is realized. and a reasonable startup mode and operation standby are formulated according to the unit grid-related performance, so that the fault risk of the power grid is effectively avoided, and great social benefits are brought to the safety and stability of power grid operation.

Description

【Technical field】 [0001] The invention relates to the technical field of generator set testing, in particular to the technical field of an active test-based primary frequency modulation online test substation system. 【Background technique】 [0002] Since the promulgation of the National Tiao No. 103 document in 2016, in order to effectively ensure the safe and stable operation of the power grid and reliable power supply, the power grids in various regions have further strengthened the work of frequency regulation management and frequency characteristic analysis. The primary frequency regulation performance of the units in the control area directly determines the rapid adjustment ability of the control area in the case of a sudden increase or decrease in frequency. Therefore, in the operation of the power grid, it is necessary to test and evaluate the primary frequency regulation performance of the unit, so that the power grid can have better primary frequency regulation perf...
