背景技术 Background technique
电网频率是电能质量的三大指标之一，电网的频率反映了发电机组有功功率和负荷之间的功率平衡关系，与广大用户之间电力设备的使用及运行安全有着极其密切的关系，但随着电力系统规模的不断扩展，负荷功率变化速率不断提高，在正常情况下，符合波动的最高速率可达600MW/分钟，同时，负荷除了瞬间波动以外，在一天中还会有较大幅度的变化，另外电网中发生的意外事故也会打破发电机组有功功率与符合之间的平衡，而传统的发电机组针对电网负荷变化调整的方法是依靠调度员的指令或依靠指定的调频厂的调节来保证发电机组与符合的平衡关系。 Grid frequency is one of the three major indicators of power quality. The frequency of the grid reflects the power balance relationship between the active power of the generating set and the load, and is closely related to the use and operation safety of power equipment among users. With the continuous expansion of the scale of the power system, the rate of change of load power continues to increase. Under normal circumstances, the highest rate in line with fluctuations can reach 600MW/min. At the same time, in addition to instantaneous fluctuations in load, there will be large changes in the day , In addition, accidents in the power grid will also break the balance between the active power of the generator set and the compliance, and the traditional method of adjusting the generator set to the load change of the grid is to rely on the dispatcher's instruction or the regulation of the designated frequency regulation plant to ensure Generator set and balance relationship with compliance.
