Abstract


With the rapid development of power system, the power quality is required to be better and better. As a result, reactive power compensation and harmonic control play important parts in power quality. During the application of all kinds of commutating equipments and a number of the nonlinear loads, harmonic currents and harmonic voltage make the power quality drop seriously. At the same time, the phenomenon of transmission line and equipments working in lower power factor occur more frequently, which threaten the stability of the power system and decrease the economic of Power Grid Company. So, it is urgent to compensate the reactive power and suppress the harmonic.In the practical application of 10kV transmission line, the presence of a large number of non-linear devices will generate a lot of rapidly changing reactive power and harmonics, causing a huge impact and destruction on the power grid. Therefore, how to carry out reactive power compensation and effective harmonic control to power grid appears imminent.This paper studies the knowledge of basic electrical theory in depth, and then introduces the basic concepts of reactive power, reactive power compensation and harmonic control in distribution grid in detail. Under the guidance of the basic theoretical knowledge, based on the actual operation conditions of Chong-Gang 10kV distribution network of a power company, this paper make a detailed analysis of reactive power compensation and harmonic suppression of the 10kV distribution network.The work in this paper includes two aspects. Firstly, this paper makes a detailed calculation of the concentration compensation of reactive power in 10kV distribution line, and then the energy-saving effect and the voltage effect are compared before and after compensation of reactive power. Secondly, a parallel passive power filter compensator is designed for the client who generates harmonic in 10kV distribution line. The filter compensation device not only filter harmonic so that the harmonic current does not flow into the power grid, but also compensate for the reactive power and improve the load power factor. The research of reactive power compensation and harmonic suppression in this paper is of some practical value for improving the security, economy and power quality of distribution network.
