电能计量装置正确接线是保证计量准确的前提,因为电能表、电压互感器(PT)、电流互感器(CT)的误差很小,而错接线造成的误差却可达到无穷大(错接线时的停走现象),真可谓一线之差,电量千万,所以在投运前或运行中应定期进行接线检查。接线检查可分两种情况:停电检查、带电检查。停电检查必较简单,它一般是对于新装或更换PT、CT以及其它计量装置投运前进行检查,主要内容是检查PT、CT的极性、变比及二次接线的核对工作-Correct wiring of the power measurement device

目前牵引变压器差动保护原理在某些因素的影响下并不能准确地区分变压器内部故障和外部故障,可能造成保护误动或拒动,危及电气化铁道系统的安全运行。针对这一现状,建立了计及铁芯非线性特性和磁滞效应而又无需铁芯的B-H曲线数据的牵引变压器模型,提出了一种通过参数辩识理论来辩识牵引变压器绕组参数实现牵引变压器微型机保护的方法。该方法能有效地区分内部故障、外部故障和励磁涌流。仿真计算表明了该方法的正确性和可行性。-Traction transformer differential protection pri

随着电力系统的发展,电网的容量,电压等级不断提高,大型高压变压器作为电能传送的枢纽,它的安全运行与否,直接关系到电力系统能否连续稳定地工作。特别是由于大型变压器结构复杂、造价昂贵,一旦发生严重故障而损坏,将给维修工作带来很大困难,造成经济上的重大损失。微机继电保护系统作为一种能反映电力系统故障和不正常状态、及时动作于断路器跳闸或发出信号的自动化设备能自动、迅速和有选择地切除故障组件,使系统免遭损坏。因此对于研制开发性能优良的变压器微机保护装置具有十分重要的现实意义。
