变电所微机自动保护系统

Microcomputer Auto protection System Used in Substations

针对继电保护存在的一些缺陷，研制了微机对供电系统进行自动保护的综合控制装置。其目的在于利用微型计算机的计算、逻辑判断和记忆等功能，使厂级变电所的保护系统更准确、可靠，从而更好地保证供电质量和经济运行。

In the light of some shortcomings shown in relaying, a comprehensively controlling device is developed, which functions as the auto protection of the power supplying system being controlled by microcomputers. The aim lies in the application of microcomputers to the calculation, logical judgement and memory so as to make this protection system in factory substation more accurate and reliable. As the result, the power supplying quality and its economical operation can be guaranteed much better than ever before. Furthermore, the data necessary for every working item can be recorded, too.
