Abstract
The invention provides the technical scheme of a statistical evaluation method for a power factor of a distribution network circuit. The statistical evaluation method in the scheme includes a plurality of steps: sequentially summing up a plurality of time periods; reading active power, reactive power, voltage information and current information of a circuit marked true in a database of the time period; computing the power factor of the circuit according to a formula; comparing the power factor with top and bottom evaluation limitations of set power factor; judging whether the power factor is qualified or not; and storing the power factor and the information about whether the power factor is qualified or not. By the aid of the method in the scheme, the power factor can be timely and reliably obtained, reliability of data is ensured, safe, high-quality and reliable operation of a distribution network is ensured more effectively, and great indirect economic and social benefits are generated.
