Abstract
The pollution of the common connection point (CCP) in the power grid is the result of the interaction of multiple harmonic sources. In order to more accurately and fairly divide the harmonic responsibility and harmonic influence of each harmonic source at the CCP, a comprehensive evaluation method considering the user’s harmonic tolerance and grid loss is proposed. Through power flow calculation and correlation analysis, the influence degree of multi-harmonic sources on the common connection point is divided. Considering the degree of harmonic tolerance of general users on the user side and the network loss factors on the grid side, the multi-harmonic source access distribution network is comprehensively evaluated. Combined with the power flow calculation results and the harmonic compatibility level of the distribution network, a comprehensive evaluation index is formulated. This method can objectively evaluate the influence degree of the harmonic source on the distribution network, and has certain guiding significance for the location selection of the harmonic source access to the distribution network, the harmonic responsibility allocation of the multi-harmonic source access to the distribution network, and the subsequent harmonic control.
