Study on the high precision frequency measurement algorithm in the mine intelligent power supply system
To solve the problem of the error of frequency measurement algorithm with time-varying frequency in mine power supply system, an improved software zero-crossing algorithm is proposed.The relationship among the phase angle, the time and the frequency of the voltage of the system is established.The re...
