AN APPROACH TO REAL-TIME MEASUREMENT OF MULTI-CHANNEL PHASOR SIGNALS

In this paper a new approach to real-time measurement of multi-channel phasor signals is presented. Techniques of polynomial approximation and computer-aided test are made use of. It is shown that this approach has some significant adventages over the conventional approach with analog circuits. In this paper, the measurement principle,system implementation,assembly programming and error analysis for the approach are given.The effectiveness of the approach is demonstrated by an example.
