| High frequency switching DC power operation system plays an important role in the power plant and substation, it is mainly for the control signal protection and automatic device and circuit breaker electromagnetic switch, DC motor, DC power,emergency lighting supply to provide DC electrical source. This topic is based on the analysis of the status quo of the development of China's high frequency switching power supply system in recent years. The designed controller is intelligent monitoring and management of the high frequency switching DC power operation system, effectively guarantee the stable operation of the power operation of DC power supply system, provides a powerful guarantee for the safe and efficient operation of electric power system.The controller is designed with International Electrotechnical Commission(IEC) standard, and the operation status of the DC power supply system is monitored by the controller, which ensures the safety, reliability and stability of the power system. In this paper, based on the characteristics of DC power supply system, the intelligent controller based on MSP430F149 single chip microcomputer is the core of the control system. Discusses the basic design principle of special equipment controller of DC power supply system and realization method of the substation automation system, realizes the real-time acquisition, processing and control of data of DC power supply system of electric power operation, and the intelligent management of battery.This paper presents the application background, system composition, function characteristics, working principle, software and hardware design and detailed design of high frequency switching DC power operation system controller and through rigorous testing and verification. The alternating voltages, bus voltage, bus current, battery voltage, battery current real-time measurement and monitoring of high frequency switching DC power operation system which intelligent management of battery charge and discharge, and monitor external charging module state, automatic diagnosis, operation of power DC power supply automatic control system. The DC power supply system, teleindication, telemetering, remote control, remote control function of "four remote". |
