电网电气功率二次接线校正的程序算法
|
摘要
电气设备功率是变电站自动化系统中的重要遥测量,生产过程中会出现功率量测错误的情况,多与测量回路有关。功率测量回路接线正确与否影响着功率的数据质量和电能表计量的准确性,功率测量回路接线的校正,有条件的一般是采用校验仪调整。《电气功率测量二次接线校正的程序算法》,使用matlab编程语言工具,对电气设备进行建模,模拟两表法和三表法测量功率原理,编制程序计算不同电压、电流组合下的功率、相角差,通过对比计算值与实际值进而帮助检修人员查找接线错误的原因。
The electrical equipment power is an important telemetry in the substation automation system. In the production process, power measurement errors may occur which are mostly related to the loop.The correctness of the circuit wiring affects the data quality of the power and the accuracy of the meter calibration. The calibration of the power measurement loop wiring is generally adjusted by the calibrator.In this paper, the matlab programming language is used to model the electrical equipment,simulate the two-meters and the three-meters test and calculate the power and phase angle difference under different voltage and current combinations, it can also help the maintenance personnel by comparing the calculated value with the actual value to find the cause of the wiring error.
