变电站综合自动化技术（Substation integrated automation technology） The substation integrated automation system is to achieve two of substation equipment by use of advanced computer technology, modern electronic technology, communication technology and information processing technology (including relay protection, control, measurement, signal, fault recorder, automatic device and remote control device etc.) the function of re combination, the optimization design of the substation operation of all. Equipment for the implementation of monitoring, measurement, control and coordination of an integrated automation system. It is a measure to improve the safe, reliable and stable operation level of substation, reduce the cost of operation and maintenance, improve the economic benefits and provide high quality power service to users. With the rapid development of automation technology, communication technology, computer and network technology, substation integrated automation technology has been developed rapidly. At present, the substation integrated automation system is widely used for monitoring, substation primary equipment and two equipment through the background monitor measurement, recording, and processing all kinds of information, realize the remote control operation function of main equipment of substation. However, in the actual use of the process also appears some problems, through analyzing the various integrated automation system are summarized, analyzed, analyzed the common problems of the substation automation system in the actual work of. First, the existence of problems 1., poor anti-interference ability. The interference signal mass background monitoring would often upload some wrong, which seriously disturbs the monitoring personnel to judge and monitor, sometimes omit a portion of a large amount of information, and it is part of this information is missing, it may be the key information, cause on the safe operation of substation, and these disturbances may evolve i
