Design And Development Of Remote Centralized Control System For The Booster Station Of The Wind Farm Based On CIM Model

Wind power generation has been widely used in many countries around the world with its advantages such as abundant,clean and renewable energy,wind power generation technology is becoming more and more mature.But because of small scale,single wind fan and a large number of sites scattered in the remote and harsh environment,which limits the development of wind power industry to a certain extent.In recent years,the concept of centralized monitoring system for wind farms is proposed,and the integrated platform of centralized monitoring and control is set up to realize the centralized management of multiple wind farms.However,there are still some restricting the further development of wind power industry,such as the grid can not realize the unified control of the same area of wind farms,failure can not be pre sentenced,emergency operation and maintenance can only be carried out,the management mode of spare equipment is obsolete.,cannot achieve full life cycle management;operation and maintenance related data analysis is not standardized.In view of the deficiency of the existing centralized control platform mentioned above,this paper presents a design and development scheme of the remote centralized control system for the booster station of the wind farm.The equipment of wind farm booster station centralized monitoring and dispatching management,production management,alarm,fan fault warning,reliable communication to the dispatching information,upload data dispatching need,and implement the dispatching and control commands issued by the end of.Firstly,the design of the wind power booster station monitoring system,according to the design principle and function requirement design system;each subsystem of the system is designed on dispatching automation and two safety protection;according to the design,the corresponding hardware configuration and software configuration are given according to the design scheme.Secondly,the application of CIM model to map database of power system and related equipment;IEC61970 CIM model was introduced;through between classes in CIM model three kinds of relation: generalization,association and aggregation are analyzed;Mapping Generalization,association and aggregation in database tables is realized with the foreign key the related database tables;part of the implementation of the power equipment and the amount of the model based on the CIM measuring point correlation;realize integrative operation in platform software.Thirdly,the system architecture of wind farm equipment access is designed,various data sources on the wind farm side are collected to be described,various data source access methods,communication protocols and other specific details are designed;finally,the data collection is realized on the system platform software.At the end,the fault of wind power booster were analyzed in the MATLAB simulation environment of the single-phase ground fault,respectively,to simulate the influence of this type of fault on the wind turbine simulation from the rotor current,active and reactive power angle,in the proof of its harmfulness also reflects a set of control system for active booster station the role of the safe operation of wind generators.
