Research On Monitoring Technology Of Modularization Inverter

Digitalization, intelligentization, and monitoring, which are tendency, are very important for improving the reliability of power system.This paper mainly studies intelligent monitoring technology of inverter. A methodology composed of Controller Area Network (CAN) field bus which is implemented with Digital Signal Process (DSP) is proposed and applied to inverter monitoring system based on the analysis of developing tendency, reliability and stability of the monitoring system. In terms of the resource of the DSP controller chip, this paper researches systematically and penetratingly the realization of hardware and software of each function module of the system etc., and gives the concrete realization project. The hardware of the monitoring system mainly consists of the DSP controller, nonvolatile memory, LED, clock management, keyboard interface, SCI communication units and CAN communication units. The software of the system includes the realization of the monitoring software of PC,SCI communication module, CAN communication module, man-machine interface and nonvolatile information management module etc..The detailed designs of hardware and software of monitoring system are presented in this paper, and the feasibility and effectiveness of system are verified by experimental results of the prototype.
