摘要
根据变电站母线电压信号频率稳定、在一定的时间内频率基本不变的特点,提出了一种同期新算法,该算法与常规算法相比具有运算量小,同期速度快,同期精度高,抗干扰能力强等优点,非常适合在变电站应用。
The paper puts forward a new arithmetic of synchronization based on the analysis of voltage signal on substation synchronizing operation. Compared with general arithmetic, this new arithmetic has lots of virtues such as less operation data, higher synchronization speed and precision, and strong ability of anti-jamming, so it is believed suitable for the new arithmetic to be applied in substations. The paper finally analyses some frequently appeared problems and then bring forward an integrated solution.
