A New Adaptive Load Rate Approach of Transformer in Power Grid Monitoring System

在电网集中监控模式中,变压器负载率监视所采用的传统负载率计算方法受变压器中、低压侧开关遥测采样正确性的影响。本文利用调度技术支持系统的网络拓扑分析,引入开关状态参数和主变压器状态参数,提出一种主变压器自适应负载率算法,并通过仿真模型进行仿真验证,结果表明该方法能正确反映变压器负载率,并且不受变压器中、低压侧开关遥测采样正确性的影响,对科学调度、精细监控具有重要意义。

Under centralized monitoring model for power grid, the traditional calculation method for monitoring transformer loading rate is influenced by measurement value sampling of medium voltage side and low voltage side circuit breakers. Based on network topology analysis in regulation technical support system, switch state parameter and transformer state parameter is introduced. A new adaptive loading rate approach is proposed and simulation model verifies the effect of this model. Through this simulation model, the adaptive loading rate algorithm can correctly get the load rate of transformer, which is not influenced by measurement value sampling of medium voltage side and low voltage side circuit breakers. The method is important to scientific regulation and careful monitoring.
