  1. Abstract : there are only two set values ( 30, 45 ) for interior angle of the stimulated directional power relay as the protection in phase to phase short circuit fault. an accurate setting formula for interior angle of the microprocessor - based directional power relay as the protection in phase to phase short - circuit fault is proposed and analyzed, users can set as a calculation value or at least an optimum in the formula. therefore the operation sensitivity and reliability of the directional relay would be improved greatly. the opinion is new and practical

    文摘:保護相間短路的模擬式功率方向繼電器內角的整定值只有兩個( 30 、 45 ) ,用戶只能在這兩個值中選其一;分析並提出了保護相間短路的微機型功率方向繼電器內角的準確整定計算公式,用戶可以整定為該公式的計算值或至少為最合理的值,從而能顯著提高方向繼電器的動作靈敏度及可靠性,具有新見解及應用價值。
  2. The chongqing electric power load system was set up in 1992, and by 1996, a control center composed by novell network, six bi - directional relay transmit stations, 2 unilateral transmit stations and 1260 diversified terminals have been established, which covered areas managed by the former electric power bureau of chongqing. the system scope of the established electric power system was on the top place among the large and middle cities over the country

    重慶電力負荷控制系統始建於1992年,到1996年時,已建成了一個由novell網路構成的控制中心、 6個雙向中繼轉發站、 2個單向轉發站、各類型終端1260多臺,覆蓋原重慶電業局所轄供電區域。系統規模在當時全國各大中城市建立的電力負荷系統中居首位。
