Abstract

This paper presents the personal computer (PC)-based LabVIEW as software to develop the algorithm of the robust complex extended Kalman filter (RCEKF) for detection of the parameters of voltage signal in power systems. The hardware of this paper is to take sample-and-hold card and DAQ (data acquisition) card for extracting the datum from the outside system to the PC, the program computes the amplitude, frequency and phase of the voltage signal with RCEKF. For validating the performance of RCEKF in this paper, the voltage signal from function generator and laboratory are applied to check the feasibility of algorithm firstly and then this application was also used in the TPC (Taiwan Power Company) secondary substation in Sijhou, Taiwan.

 

Key words: Complex Kalman filter, robust algorithm, voltage distorted signal, LabVIEW.
