produced by Dongfang Electronics, which has the function of encapsulating the operating system after startup. The monitoring software encapsulated operating system means that when the background monitoring machine is started for the first time, the monitoring machine automatically starts the operating system and continues to start the monitoring software until it starts to the monitoring software interface. If the monitoring software is stopped, a password needs to be entered. Only those who master the password can stop the monitoring software and enter the operating system. At present, some background monitoring software of substation automation system does not have this function, which should be solved jointly with the manufacturer&＃39;s technicians. The monitoring software encapsulates the operating system function, which is very effective in preventing the background monitoring machine from being used and damaged by others. When selecting the background monitoring software, we should pay attention to the selection of products with this function to improve the safety and reliability of the background monitoring system. (3) Industrial control computer shall be selected as the background monitoring machine. Because the background monitoring machine requires real-time operation, large amount of data processing, fast response speed and strong electromagnetic environment, general ordinary computers cannot meet the requirements, and high-performance industrial control computer shall be selected. The high-performance industrial computer can work in a strong electromagnetic environment, has strong anti-interference performance, can run in real time, and has good working stability of hardware equipment, which can meet the requirements of substation background monitoring system. At present, in some substations, due to the extensive use of commercial computers, home computers and other computers, the background monitor has been damaged and can not work. highThe performance industrial computer can ensure the safe and stable operation of the substation background monitoring system. (4) The background monitoring machine shall be equipped with uninterruptible power supply. In some substations, the background monitoring machine is not equipped with uninterruptible power supply, and the AC power supply of station transformer is used. Using the AC power supply of station transformer has the following disadvantages: first, when the system is powered off, the background monitoring machine loses power and cannot work; Second, the AC voltage of the occupied transformer fluctuates greatly, sometimes the voltage quality is unqualified, sometimes the voltage is high, the computer is burned, sometimes the voltage is low, the computer can not work, and can not provide qualified power supply to the background monitoring machine; Third, when the primary fuse of station transformer is blown, the background monitoring machine loses power; Fourth, when the 10kV system is grounded, the AC power supply of station transformer is seriously disturbed by harmonic, which affects the normal operation of background monitoring machine. At present, some manufacturers produce DC inverter and AC inverter. The DC battery in the station is used as the DC power supply of the inverter, which is supplied to the background monitoring machine after AC inverter. The capacity can be 500-1000va. With this inverter, there is no need to purchase another DC battery, which saves investment and has good effect. (5) The real-time
