(Summary description)"Background data is uploaded correctly and can be monitored in real time." On March 15, zhaowenchang, a staff member of Changji power supply company in Xinjiang, said in a background data transmission test at 110kV Daxiqu substation.
This marks the first batch of active interference system of over voltage in Xinjiang distribution network, which is put into operation in Changji, Xinjiang.
It is reported that most of the power systems under 35 kV in China adopt neutral point ungrounded operation mode. If the line is grounded instantaneously due to lightning stroke or other reasons, the sound phase voltage will rise suddenly and generate a large inrush current, which will cause the voltage transformer to burn down, and the people's livelihood power and the safety of the power network can not be guaranteed. The project adopts fast algorithm, fast response speed and obvious intervention effect, which can effectively solve the frequent fuse fuse problem of voltage transformer, ensure that there is no leakage judgment and improve the reliable operation of the power grid.
Meanwhile, the project adopts wireless transmission and high-speed transmission of 4G and 5g network to achieve the function of remote online monitoring. The staff of the company can not leave home to understand the operation status of the equipment, make up the blank of electromagnetic voltage transformer in this field, record the fault waveform, and then accurately judge the fault type, greatly reducing the failure rate of the equipment.
At present, the device has been installed and used in 10 substations in Changji District, Xinjiang, and has achieved good application results. The operation of the device means that the staff can monitor the operation status of the equipment in the substation remotely and make fault prediction by real-time data, ensure the residents safe and stable power consumption in 24 hours, and improve the reliability of the substation equipment operation.
