Abstract

The synchronous sampling method is widely used in precision measurement of distorted power. However, strictly synchronous sampling can not he fulfilled in the real life application. So, large leakage or truncation errors may occur in the measurement results due to asynchronous sampling. This paper proposes a new automatic compensation algorithm for quasi-synchronous sampling, which can decrease, even eliminate the leakage errors from the quasi-synchronous sampling process in measurement results. Computer simulations have verified the correctness of the proposed algorithm
