Example Embodiment

[0110] Example

[0111] System operation requires the support of several processes, including network configuration and debugging process qconfig; database configuration process DBGui; network monitoring process Net; pre-data acquisition and communication protocol management process Fert; data processing process Scada; data saving process ScadaSave; from Fert The data is sent to the DataSvr process of Scada, and the processes cooperate with each other to make the system run stably. The working steps of the system are as follows:

[0112] (1) Configure network nodes

[0113] Use the qconfig network configuration tool to build network nodes, set up the main server server1, standby server server2, and workstation client1. Three processes of the SCADA server are configured, including DataSrv, Scada, and ScadaSave, a fert process of the FERT server, and each process is set to a guardian state.

[0114] (2) Configuration database

[0115] Configure the protocol set of the communication pro...

Abstract

The invention provides a wind power plant reactive voltage comprehensive control system and a wind power plant reactive voltage comprehensive control method. The system comprises a front-end processor subsystem, a network subsystem, a database subsystem, a reactive regulation module and a man-machine interface module. The wind power plant reactive voltage comprehensive control system receives a control objective delivered by a master station at regular time, carries out optimal balance adjustment on the reactive power of various reactive equipment according to the operating conditions and the reactive adjusting capacity of a fan, a SVC (static var compensator)/SVG (static var generator) and other reactive adjustable equipment and on the premises of meeting system stability and equipment safety, so that the requirement on voltage controllability is met, and the stability margin of a system is also improved.

Description

technical field [0001] The invention belongs to the technical field of electric power system voltage automatic control, and in particular relates to a wind farm reactive voltage comprehensive control system and method. Background technique [0002] With the rapid development of wind power in China, my country's annual newly installed wind power capacity and total installed capacity have leapt to the forefront of the world. my country's wind farms are scattered in different areas, and there are many types of grid-connected wind turbines, and the capacity of wind farms is relatively large. Compared with traditional thermal power plants, wind farms generally have shortcomings such as decentralized control, low automation level, and weak dispatch control. In terms of voltage and reactive power configuration and control, some wind farms have insufficient reactive power configuration capacity and lack of control means, resulting in a low pass rate of bus voltage at grid-connected...
