| Abstract: | This paper analyzes the
relation between the resistive current error and the harmonic content of the power system
and presents a method of multi-coefficient compensation. Simulation and numeral
calculation show that this method can effectively eliminate the capacitive current caused
by the harmonic content of the power system, the resistive current measurement are more
accurate, moreover it can be achieved easily with hardware and software and the theory is
useful to MOA on-line monitor effectively. |
