information. The telecontrol data and information of some substation automation systems are sent to the dispatching master station through the background monitoring system. When the background monitoring system cannot work normally, the telecontrol data and information cannot be sent, This method is not conducive to the transmission of telecontrol data and information. Telecontrol data and information shall be sent directly to the dispatching master station in the communication unit of the protection and monitoring system, which is not controlled by the background monitoring system. Since the transmission of telecontrol data and information is controlled by the background monitoring system, several substations have stopped transmitting telecontrol data and information to the dispatching master station because the background monitoring machine can not work normally. This situation can only be handled by the manufacturer. (2) Sending, receiving and processing of telecontrol data and information at present, some substation automation systems do not have strong ability to send, receive and process telecontrol data and information, which is mainly reflected in: they can not upload protection setting value and main transformer gear, and can not correctly receive and process switch remote control operation, modification setting value, main transformer gear adjustment and other functions of dispatching master station. Because of this problem, the automation of substation is greatly affected, which is not conducive to the remote operation of equipment. 3. To sum up, the above problems are some serious problems in the actual operation of substation automation system. Some can be handled by themselves, most need to be handled by manufacturers, and some can not be handled by manufacturers. The existence of these problems is not conducive to the safe, reliable and stable operation of substation. When selecting the substation automation system, we should pay attention to whether the above problems exist and whether the overall function of the substation automation system is complete. Substation automation system is the core of substation. Choosing a set of high-quality substation automation system is very important for the safe, reliable and stable operation of substation.
