The Process And Analysis To The Unusual Wiring Of Electrical Energy Metering Mechanism

In the electrical energy measurement process, the electrical energy metering mechanism cannot reflect correctly the actual electric quantity making the wrong measurement to be called the unusual electrical energy measurement. For fairly, reasonably measure electrical energy, maintain the sender, the power supplyer, the user's economic interest,it must promptly diagnose and correct the unusual electrical energy measurement and takes the effective measure.The electrical energy metering mechanism including each type's measurement with the voltage, the current transformer ,the secondary circuit, the electrical energy cabinet, the electrical energy box and so on. Any part occurs exceptionally can affect the accurance of the electrical energy measurement,and also cause the fairness between the power supplyer and the user.The paper regarding the problem of the unusual electrical energy measurement do the following work:(1) study principly to the problems of the unusual metering mechanism, analyze the reasons of it's and study each kind of measurement principle.(2) Classify the unusual electrical energy metering mechanism according to the differences between the electric circuit and the electric object .Summarize the vector figure of each wiring situation. Propose the phase angle table. Explaine the method of calculate Correction coefficient .And to use the phase angle table to analyze the unusual electrical energy metering mechanism wiring simplify the parsing process, reduce the computation difficulty, enhance the usability.(3) The paper based on the B/S architecture to complete the design of the electrical energy metering mechanism analysis system. It include the correction electric quantity computation module, and can process and calculate almost 6000 kinds wirings including single-phase, three-phase three wiring, three-phase four wiring. The system has put into use in Shuozhou power supply subsidiary company, Xinzhou Power supply Subsidiary company in Shanxi, and has indicated stably, effectly and conveniently. At last display the main pages of the system.
