| Popis: | An efficient system for the compensation of current transformers over a wide frequency range is presented. The proposed technique is based on digital signal processing and inverse modeling using the frequency domain approach and Wiener filtering. Since the proposed technique applies finite impulse response filtering, the compensation filter is absolutely stable. The modeling error is reduced using a small time delay in the modeled inverse transfer function, which is unobservable for the human operator. The proposed algorithm is implemented in real time using a PCI eXtensions for Instrumentation system. |
