Abstract

The reliability and performance of complex power systems with many sensors are largely dependent on the accuracy and reliability of the sensors. Thus, it is very important for monitoring and diagnosis the sensor faults. In this paper, the digital realization of polynomial chaos theory (PCT) based sensor failure detection and diagnosis (SFDD) algorithm considering parameter uncertainties has been detailed. A digital signal processor (DSP), TMS320F2812, is adopted to implement the proposed SFDD algorithm. Both hardware-in-the-loop testing and laboratory experimental testing have been done to verify the online practical application capability of the proposed algorithm. A three-stage synchronous generator with automatic voltage regulator (AVR) has been used as a case study. The control performance of AVR is guaranteed to be more reliable by the application of SFDD algorithm based on PCT. Experiment results show good consistency with the theory analysis.
