System processed has SVG or SVC equipment and the small water of scale to solve all common configurations such as prior art wind power plant, photovoltaic plant
The continuous reactive regulating power that electric group has, but be not included in can effectively participate in power grid AVC control lead to the serious wasting of resources
With the technical problems such as traditional AVC control system hardware cost height.
The technical solution of the utility model includes:
A kind of province that wind-light storage and small hydropower system participate in ground AVC control system, it includes: AVC control main website and AVC control
Substation system, straight modulation power station, Direct Modulated Power Plant, straight fire tuning power plant and AVC control sub-station system are logical with AVC control main website respectively
It crosses network connection and realizes two-way communication；Substation, wind power plant, photovoltaic plant, energy-accumulating power station and small hydropower system are controlled with AVC respectively
Substation system realizes two-way communication by network connection.
The AVC control sub-station system includes substation, wind power plant, photovoltaic plant, energy-accumulating power station and small hydropower system.
The utility model the utility model has the advantages that
The utility model, which combines wind-light storage and small hydropower system, participates in AVC control system, by wind-powered electricity generation, photovoltaic plant, storage
Energy power station, small hydropower system and substation are built into AVC substation system, participate in AVC and adjust；Solve prior art wind power plant, light
The continuous reactive regulating power that all common configurations such as overhead utility have SVG or SVC equipment and scale small hydropower system to have, but not
Power grid AVC control can effectively be participated in by, which being included in, leads to the skills such as the serious wasting of resources and tradition AVC control system hardware cost height
Art problem.
