Harmonics are the most common problem arising in power system currently. This paper introduces an intelligent instrument for integrated harmonic detection and protection in power system based on dual DSPs. The hardware structure and software modules are described in detail. A high accuracy FFT algorithm for harmonic analysis is put forward. This instrument can effectively monitor power system harmonics, as well as monitor and analyze other electrical parameters in power system automatically. Besides, the instrument can give an alarm and take protective measures timely and reliably when harmonics exceed the allowed value. Experiment results show that the instrument satisfies the requirements of real-time and high reliability, features high performance to cost ratio and high accuracy, and has broad application prospects.
