摘要
The conventional adaptive compensation of capacitor bank synchronous switching requires additional current transformers for detection of circuit breaker's making point, resulting in increased costs and installation time. This led to invention of a new algorithm that is adaptively compensates for variation in closing time. The new algorithm removes the need for current transformers or special sensors. It uses only phase voltage signals. The algorithm can be used with any circuit breaker model and independent from network's R, L, C properties. Using wavelet transform and 'Widest Frequency Band algorithm', the making point can be detected with robust to noise interference. A method is also developed to approximate the rate of decrease of dielectric strength (RDDS), which enables faster compensation adapting
