And based on the wide area measurement system,a new system frequency measurement method was proposed,in which the units rotate speed of the system was real-time measured,and then the frequency of system inertia center was calculated out.
分析了传统频率测量方法的局限性,提出以广域测量系统为基础,通过实时测量系统中各机组转速,进而计算出系统惯量中心频率的系统频率测量方法。
