浅谈微机型自切保护逻辑的标准化

Logic Standardization for Microcomputer-Based Automatic Switching Protection

微机保护利用高速、可靠和先进的数据采集系统,配合各种计算机保护算法,实现了不同的继电保护功能。微机保护应用到备自投装置中后,因各站中实际的一次、二次接线方式的不同,而产生了很多实际的问题。在解决问题的过程中,微机保护的灵活的逻辑编程的优点充分体现出来,这也为总结出最实用、最可靠的保护逻辑并规范自切保护提供了条件。

By means of the high-speed, reliable and advanced data collection system integrated with various computer protection algorithms, microcomputer-based protection can perform multiple relay protection functions. With the application of microcomputer-based protection to spare automatic switching units, many problems have arisen due to the different primary and secondary wiring modes in the substations. In the problem-solving process, the flexible microcomputer propection logic programming exhibits its great advantage, the prerequisite for the formulation of the most practical and reliable protection logic and the standardization of automatic switching protection.
