However, at the beginning of the design of the WAMS system, the monitoring of the power grid was more considered, and the control of the power grid was basically not involved. Therefore, the real-time communication protocol between the WAMS master station and the sub-station is a one-way agreement, that is, once the communication is established. The slave station only transmits data to the master station

The invention provides a WAMS-based active primary frequency modulation online test system and method. Wherein, the WAMS-based active primary frequency modulation online test system includes: an active primary frequency modulation main station system located in a regulation and control center, a PMU data concentrator located on a power plant side, and an active primary frequency modulation substation system located on the power plant side; and wherein, the active primary frequency modulation main station system and the active primary frequency modulation substation system are integrated in a WAMS system, the active primary frequency modulation main station system transmits a primary frequency modulation control command based on an offline data pipeline of a PMU data concentrator, the PMU data concentrator recognizes the primary frequency modulation control command and then forward the primary frequency modulation control command to the active primary frequency modulation substation system, and the active primary frequency modulation substation system regulates and controls a set to perform an active primary frequency modulation action based on the primary frequency modulation control command. Through the technical scheme of the system and the method, test of primary frequency modulation performance of a thermal power generating unit can be quickly achieved based on the WAMS without affecting normal operation of an existing real-time dynamic monitoring system WAMS.
Description
technical field [0001] The invention relates to the technical field of power system testing, in particular to a WAMS-based active primary frequency modulation online testing system and a WAMS-based active primary frequency modulation online testing method. Background technique [0002] For the current power grid system, when the power generation of the entire power grid is greater than the power consumption, the frequency will be higher than 50Hz, and on the contrary, the frequency will be lower than 50Hz. The power grid dispatching center often needs to control the power generation to maintain the power grid frequency around 50Hz. The primary frequency regulation performance of the unit directly determines the rapid adjustment capability of the power grid in the event 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 gr...
