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:保护相间短路的模拟式功率方向继电器内角的整定值只有两个( 30 、 45 ) ，用户只能在这两个值中选其一；分析并提出了保护相间短路的微机型功率方向继电器内角的准确整定计算公式，用户可以整定为该公式的计算值或至少为最合理的值，从而能显著提高方向继电器的动作灵敏度及可靠性，具有新见解及应用价值。
