Effective monitoring on the stability of hydropower units is the key measure to improve the safety of unit operation, increase the efficiency of plant operation and lower the costs of maintenance. Therefore, it has great significance on doing research on the stability monitoring of hydropower units. Based on prehensive summary of the features and applications of current stability monitoring system and according the functional characteristics of stability monitoring system of HOMS, we develop a stability monitoring system applying the DSP chip TMS320F2812 as its core. Combined with the emerging application, the system designed for small and medium hydropower units has high reliability, Which is integrated 32-channel analog signal conditioning and acquisition module, digital input and digital output module, frequency measuring and generating module, and LCD display module. Beside these modules, it also realizes the functions of CAN-munication and munication. This paper describes and analyses specifically the hardware designing and software developing of each module, and the developing of the main application. What’s
