变电站电能计量误差的影响因素及控制措施

Electric Power Technology and Safety Management
电能计量精度是保障电力市场公平交易与电网安全运行的核心指标。本文针对智能电网背景下变电站计量误差控制难题,从设备性能、环境适配、运行工况、管理体系四个维度展开深度分析,结合110kV及以上电压等级变电站现场实测数据,揭示互感器饱和、谐波干扰、温度漂移等关键影响因素的作用机制。通过引入电子式互感器、智能滤波算法、边缘计算监测等前沿技术,提出包含设备升级、环境改造、动态补偿、标准化作业的全流程控制方案。工程验证表明,该方案可将计量误差从1.8%降至0.42%,满足0.2S级精度要求 ...
