电力系统及其自动化复习（Power system and its automation review）

电力系统及其自动化复习（Power system and its automation review） 1. What are the functions of power grid dispatching automation system? The comprehensive utilization of computer, remote communication and remote communication technology, realize the automation of power system dispatch management, and effectively help the power system dispatcher to complete the scheduling task. 2. The main function of SCADA system is to collect, process, monitor and control real-time data. 3. The hot standby in the scheduling automation system refers to that the master backup system simultaneously gathers data and operates simultaneously. 4. Remote control operation of remote control station is divided into: remote control select remote control and remote control. 5. Purpose of reactive power optimization: control power, control voltage, control network loss. 6. Load adjustment includes reactive power and voltage regulation, active power and frequency adjustment. 7. The database management system stores the simulation quantity, switching volume and cumulative volume from various RTU. 8. The front-loader system is responsible for the interpretation of data communications and communication protocols with plant stations, RTU and bureaus. 9. Integrated automation of substations is composed of two parts: microcomputer relay protection and monitoring system. In order to meet the needs of grid dispatch, the remote information translocation information is sent in a way that requires the main station in the 1S. 11. In the power grid dispatching automation system, the task of information gathering is mainly completed by the man-machine contact system. 12. Network topology analysis is the basis of EMS advanced application software. 13. The basic form of serial communication is synchronous and asynchronous. 14. The rated voltage of the secondary side winding of the voltage transformer is 100V. 15. The resolution of the event sequence records in the distance measured by the remote technical indicator is no gre
