Study on Modeling and Measurement Technology of Dynamic Reactive Power Compensation Device for Renewable Energy Station

Abstract

At present, the measurement and Modeling Research of power system mainly focuses on generator, excitation system, prime mover and its regulation system, power load and so on. However, there is relatively little research on the measured modeling of dynamic reactive power compensation device. In the simulation calculation of power system, the dynamic reactive power compensation device usually adopts a highly simplified model, or even ignores it. The accuracy and applicability of the model are limited, which directly affects the reactive power voltage regulation capacity of renewable energy stations and the consumption of renewable energy. Acceptance. There are great differences in the characteristics of the actual equipment, which may lead to the inconsistency between the calculation results and the actual situation, the relevant power grid planning and operation will lose the basis, and the power grid operation will face great hidden dangers. In the field of field measurement and modeling of power system, the dynamic reactive power compensation device of renewable energy station lacks field measurement and modeling technology, which can not meet the requirements of accurate modeling of power system and safe and stable operation of large power grid The operation of power grid will face great hidden dangers. It is urgent to study the model and parameter technology of dynamic reactive power compensation device in renewable energy station.
