The Design And Realization Of Wind Farms Scheduling Technology Support System For The West Inner Mongolia Power Grid

In recent years, the grid in the west of Inner Mongolia220kV network, withcontinuous access to large-scale wind farm, wind effects on the network more andmore. The intermittency of wind power, random, easy to make the fluctuation of windpower is very large, the dispatching center can conduct real-time monitoring andcontrol of wind farm, will be directly related to the security and stability of powergrid and economic operation. With the scale of wind power continues to increase,large wind farms in the grid-connected power grid will be more significant impact on.Facing the wind power dispatching and the need to address the problem mainlylies in3aspects:1, power grid dispatching personnel need to master the running state of windgenerator and wattless compensation device.2, network operators need to master the wind farm in the future real powergeneration capacity, because the wind is random, intermittent characteristics, need tostudy and solve the influence of wind on the wind load.3, Power grid peak shaving problem.In order to solve the above problem, Mengxi power grid dispatching center putinto use wind power dispatching technical support system. The research contents ofthis paper mainly focused on the process of implementation of the system. In thispaper, the whole system is divided into four stages:1, according to the function of each part of the system, to determine the mainincluding wind power Supervisory Control And Data Acquisition (SCADA) system,intelligent communication management terminal, Numerical Weather Prediction(NWP) system, the wind power forecasting system of four subsystems. Therelationship between the main system overall structure and subsystem.2, The realization process and the function design of each subsystem.3, After the basic functions of each subsystems, integrate the realization ofhuman-computer interaction subsystem, all in a single workstation.
