Research on online monitoring system of distribution transformer harmonic additional loss
摘要
Abstract
Online monitoring of distribution transformer harmonic loss is an important approach to providing decision-making for thedetermination of the high-loss transformer and ensuring the transformer economic operation. Γ circuit model is introduced to improve the transformer harmonic additional loss model and the accuracy of the algorithm is effectively improved by using the ratio of winding loss and eddy current loss to compensate transformer core loss caused by harmonics. Based on which, online monitoring system for transformer harmonic additional loss is designed. System host controller adopts DSP2812 which can detect transformer operating parameters and supply real-time data for monitoring transformer harmonic additional loss through serial port. The system software is developed by object-oriented Visual C + + 6.0, including data display module, serial port operation module and transformer parameters setting module. The analysis of the experiment indicates that the result of monitoring system is correct.关键词
