关于 继电保护的英语翻译

Protective relaying is that area of power system design concerned with minimizing service interrupter and limiting damage to equipment when failures occur. The function of protective relaying is to cause the prompt removal of a defective element from a power system. The defective element may have a short circuit or it may be operating in an abnormal manner. Protective relaying systems are design to detect such failures or abnormal conditions quickly and to open a minimum of circuit breakers to isolate the defective element. The effect of quick isolation is threefold:(1)it minimizes or prevents damage to the defective element thus reducing the time and expense of repairs and permitting quicker restoration of the element to service;(2)it minimizes the seriousness and duration of the defective elements affecting on the normal operation of the power system; and (3)it maximizes the power that can be transferred on power systems. The second and third points are of particular significance because they indicate the important role protective relaying plays in assuring maximum service reliability and in system design. The power that can be transmitted across system without the loss of synchronism is the function of fault clearing times. It is apparent that fast fault clearing times permit a higher power transfer than longer clearing times. High-speed clearing of fault can be often provide a means for achieving higher power transfers and thereby defer investment in additional transmission facilities.

继电保护是电力系统的服务，最大限度地减少和限制灭弧设备损坏故障发生时，有关设计区域。继电保护的作用是使从电力系统有缺陷的元素，可迅速清除。有缺陷的元素可能发生短路，也可能不正常地运作。继电保护系统是设计来检测故障或异常情况迅速打开一个断路器最低孤立缺陷的元素。迅速隔离的效果是三个方面：

（1）减少或防止损坏的缺陷元素从而减少维修时间和费用，并允许更快的恢复服务元素;

（2）它最大限度的严重性和持续时间有缺陷要素对电力系统正常运行的影响;

（3）有最大化，可以在电力系统的权力移交。第二和第三点是特别重要的意义，因为它们表明了继电保护的重要作用，在保证最大的可靠性和服务系统设计了。即可以跨系统，传送未经同步损失的力量就是故障清除时间的功能。很明显，快速故障清除时间较长允许比结算倍移交权力。高速清除故障经常可以提供更高的功率为实现转移，从而推迟额外的输电设施投资的手段。
