Intelligent Controll And Design Of Controller Of Low-voltage Circuit Breaker Based On The Dual Msp430

The low-voltage circuit breaker is important in power system control and protection equipment, and maintenance of power system security, stability and reliable operation plays an important role. It is important in power system protection requirements of the development to improve the safety, reliability and the circuit breaker highly intelligent, which is also the purpose of this paper.This paper well-designed TI company MSP430F147as the core dual-CPU circuit breaker intelligent controller on basis of in-depth studies the development of intelligent circuit breaker at home and abroad.Firstly, this paper discusses the hardware frame structure of the device to determine the design principles of the microcontroller and peripheral functional unit, system hardware and software design, the controller unit to the MSP430F147microcontroller core processor, dual-core model, on the one hand, the intelligent controller circuit breaker body and the automatic monitoring of the network parameters, on the other hand the functions of the intelligent controller intelligent operation of circuit breakers.Then detail the main function of the intelligent controller module works and a variety of measurement device is designed, the protection algorithms and methods are discussed in detail.In Communication aspects, the paper, Achieve Circuit breaker and host computer communication with the CAN bus. And Telemetry, remote adjustment, remote control, remote "remote" feature. The software is modular in design, each module is relatively independent of a particular function, easy to maintain and add new features, and flexible debugging convenience.Finally, various anti-jamming measures of device is illustrated in the hardware and software, and take a test for the protection of intelligent controller to obtain the experimental data for error analysis. Finally, the function of controller have been authentication to meet the request of design.
