| 摘 要： | 针对传统电力测量仪表存在的不足,改进微机保护装置功率算法,通过对微机保护装置常用算法的分析,提出一种利用两功率表法,采用长数据窗(一周波)瞬时量相乘积矩形积分以求取一周波线路的平均有功、无功功率的算法.编制了能够应用于发电厂、变电站等任一进线、出线,以及系统间联络线的三相三线制系统的有功功率、无功功率的测量程序,并对程序可行性进行了验证.

| Abstract: | The disadvantage of traditional power instrumentation is analyzed,to improve the algorithm in microcomputer protection and the routine algorithm in microcomputer protection is also analyzed.A new method named two-power meter is presented.Active power and inactive power can be calculated through long data-window algorithm.A program is worked out for power measurement,which can be applied in power plant, substation and etc,and the power can be calculated of any three-phase three-line system in any enter-line,out-line and in tie-line among power system. |
