Problems solved by technology

[0002] At present, the fault detection and line loss analysis products that are widely used in the station area are generally divided into three-phase electric energy meters for low-voltage measurement, high-voltage meters for high-voltage measurement, low-voltage circuit breakers for low-voltage protection equipment, and distribution automation terminals for high-voltage protection ( DTU / FTU), transformer protection differential protection and other equipment, although the products of this scheme can also complete certain functions of fault detection and line loss analysis, but there are still many problems in field application: 1) Install independent each A variety of high-voltage and low-voltage protection and monitoring equipment, analog quantities such as voltage and current are connected to different devices, the wiring is complicated, implementation and maintenance are difficult, and the cost is high, which is not conducive to mass promotion; 2) Independent high-voltage and low-voltage equipment occupies volume and space More, which is not conducive to the beauty of the city and the intensive use of land; 3) High-voltage metering and low-voltage metering are separated into independent equipment monitoring, and uploaded to the master station to calculate and analyze line loss, which requires high processing speed and resources for the master station, and low real-time performance; 4) The monitoring equipment in the station area generally has no protection function, and cannot monitor and control the internal faults of the transformer and the faults in the station area; 5) The power distribution automation terminal has a high-voltage protection function, but it cannot be connected to low-voltage measurement, and does not have the detection and control of internal faults in the transformer. protection, and does not have the real-time analysis function of high and low voltage line loss
[0004] Therefore, there are deficiencies in the existing fault control technology in the station area, and it needs to be improved and improved.
