Application and Economic Analysis of Automation Technology in Single-Phase Grounding Protection of Distributed Photovoltaic Power Generation Distribution Network
Based on the method of analysing the characteristics of phase current mutation amount,an automation system architecture based on MPC8313 processor and FPGA is constructed to achieve efficient detection and location of faults.Through practical application in a seaside city in the southeastern coastal region,it is found that the automation system significantly shortens the fault response time,reduces the average annual number of faults,and improves the reliability of power supply.The economic analysis shows that the automation technology solution has high net present value(NPV)and return on investment(ROI),which proves its economic benefits and investment value.
