Based on the experimental platform of marine power station, the design of the collection circuit was presented and the electrical parameters such as voltage, current, frequency and phase were collected by taking digital signal processor (DSP) in type of TMS320F2812 as the core controller. As regards the site jamming signal existed in power system, the full-wave differential Fourier algorithm was applied to improve the sampling process. It could completely eliminate the DC component and suppress the aperiodic component, while obtaining the accurate fundamental component. Furthermore, the necessary conditions for establishing an effective monitoring system were provided. Combined with the touch screen in type of WEINVIEW MT8100i, the data monitoring and alarm display of the marine power station were realized. The designed data collection and monitoring system can be continuously and stably operated on the experimental platform, which verifies the feasibility of the design.
