摘要
简介了PSL 6 0 2微机线路保护与WBZ 12 0 2B微机变压器保护装置人性化、透明化、开放性的特点。针对调试中出现的一些现象 ,从装置软件设计的角度给予深刻的剖析 ,如 :保护模件控制字的整定对试验结果的影响、复压闭锁方向过流保护方向元件动作范围的确定、零序方向过流保护方向元件电压电流的获取 ,以及关于测试仪和保护调试分析软件PSVIEW使用中的一些特殊问题等。并对差动保护中TA二次电流相位校正软硬件手段的实现差异和
The convenient, transparent and open characters of microprocessor based protection equipment PSL 602 for transmission line and WBZ 1202B for transformer are presented.Some problems occurred in their test are discussed,such as:the influence of control byte setting upon test results;the action area angle determination of direction component for the compound voltage block direction overcurrent protection; the voltage and current acquisition of the direction component for zero sequence direction overcurrent protection; the use of PSVIEW analysis software for test equipment and protections; and so on. Furthermore,the difference between hardware method and software method for rectifying the current vector TA’s secondary side in differential protection and the cause of …3∥…are explained theoretically.
