摘要
Abstract
To address the problem of computation insufficiency and data overflow in calculating high-precision elec-tric power quality related parameters using fixed-point DSP,we propose the optimization algorithm for electrical pa-rameters. According to the characteristic of fixed-point DSP that has maximum 32 bit data length and is efficient in multiplication and accumulation,we improve the way of implementation of electrical parameter algorithm on the DSP, then present the derivation of algorithm optimization and analyze the error before and after optimization. Finally,the experiment verifies that after optimization,the algorithm can effectively prevent data overflow and reduce the amount of calculation,therefore avoid the secondary development caused by the replacement of DSP.关键词
