| description | The invention provides a remote synchronous measurement system for monitoring the fault of a current collection line of a wind power plant, and the system comprises a plurality of synchronous measurement units which are respectively disposed in corresponding fan box transformer cabinets. The synchronous measurement unit comprises a main processor which is responsible for controlling the synchronous measurement unit and comprises the setting of sampling period time; the GPS module is used for receiving a satellite second pulse signal; the counter module is used for generating a first count value, resetting the first count value based on the second pulse signal output by the GPS module and restarting counting; the comparison module is used for generating corresponding counting time based on the first counting value, and generating a synchronous sampling pulse signal and a zero clearing signal when the counting time is equal to the sampling period time; and the A/D conversion module is triggered and started by t |
