配变监测系统（Distribution transformer monitoring system） **************** Hua Guan public statement monitoring system of distribution transformer System overview The system can monitor and collect data of public distribution transformers in real time, provide a channel for meter reading and residents collection, and protect public distribution transformers. The system has the functions of line loss analysis, reactive power flow analysis, voltage qualified rate statistics and so on. system function 1. data acquisition function: Acquisition of reactive power, A, B, C three-phase voltage, A, B, C, N four line current, Power factor, transformer oil temperature and oil level. 2. event logging function: 1) when a power failure or phase failure occurs, the event record is recorded, and the terminal can automatically record the power failure or phase failure Up and down time, can count the accumulated time and report. 2) when a (or two) open circuit or short circuit occurs, it can be reported immediately and recorded. 3) when the voltage and current are limited, the event record is recorded and the over voltage or electricity is automatically recorded The starting and ending times of the flow and the over limit values are reported. 4) oil temperature is too high, oil level is too low to record and report. (alternate) 3. statistical function: 1) daily A, B, C three-phase voltage, current maximum, minimum and its occurrence time. 2) daily maximum demand of A, B, C and its occurrence time. 3) voltage qualified rate statistics and power supply reliability statistics. 4., line loss analysis, reactive power flow analysis and load forecasting function. 5 provide a channel for the residents collection system. The 6. master station system can connect with the MIS system and GIS system of the electric power company, provide more perfect data for it, and provide a valuable reference for the capacity expansion and transformation of the distribution network. 7. historical data query function.
