Fast Analysis Method of Reactive Power Balancing and Critical Power Flow and Application to Study Controllable Shunt Reactors Requirement in UHV Grid
摘要
Abstract
With the planning and constructing of the ultra high voltage (UHV) grid of China, the controllable shunt reactor (CSR) attracts more attentions as an important control measure for var and voltage. Therefore it is urgent to analysis and study the deployment of UHV CSRs scientifically. In the paper, firstly, the feasible var balance principles were proposed;secondly, the quantitive relationship between the var demand and active power going through the reactance element was analyzed in depth. Furthermore, only based on active power flow, the fast analysis method of substation-centered var balance and critical power flow was proposed and applied into the study of the deployment of the UHV CSR and its requirement and location. The method can not only be applied into the fast quantitive analysis of the given power flow pattern, but also can be used to obtain the relation curve between the critical power flow and the transformer load rate, thereby, the adaptability of the study conclusions to the various load levels and power flow patterns is increased. Finally, the requirement and the deployment of CSRs in UHV‘Dongzong’ transmission project were studied with the proposed method, and the conclusions and recommended deployment schemes were given, which provides the technical basis for the pilot project of UHV CSR.关键词
