Description
Technical field
The present invention relates to the integrated automatic voltage powerless control system in ground county.
Background technology
At present domestic have many users using the idle control of automatic voltage (AVC) system; But the electrical network scope of these system regulations often is a certain zone or certain two electric pressure of area power grid; Area power grid possibly need to arrange quite a few cover AVC system (have city office, county telephone central office), between system there is not or extremely limited (being only limited to some interconnection or critical point alternately) alternately strategy.Therefore, area power grid lacks the complete AVC system of model, and the control strategy of being made makes that against electrical network whole systematicness, correlative character optimizing effect is affected, in addition each other or with higher level's line voltage reactive requirement be contradiction.
Summary of the invention
The object of the present invention is to provide the integrated automatic voltage powerless control system in ground county; Can effectively solve existing area power grid and lack the complete AVC system of model; The control strategy of being made makes and optimizes the affected problem of effect against electrical network whole systematicness, correlative character.
In order to solve the problems of the technologies described above; The present invention realizes through following technical scheme: the integrated automatic voltage powerless control system in ground county; Comprise that the provincial longitudinal data that links to each other successively transmits mutual device, vertical transmission server, AVC server; Said AVC server links to each other with ground county regulation and control server through the wire communication net; Said ground county regulation and control server links to each other with at least one data acquisition server at county level with at least one city-level data acquisition server; Said city-level data acquisition server and this city administration power plant production scheduling server links to each other, and said data acquisition server at county level links to each other with this county administration power plant production scheduling server, and said ground county regulates and control server and links to each other with all power plant's production scheduling servers inside the province.
Preferably, said wire communication also is connected with monitoring server on the net; Whether the operation of monitoring whole system is normal.
Preferably, said wire communication also is connected with dispatch server on the net; Conveniently regulating and controlling.
Preferably, said wire communication also is connected with ground county regulation and control data server on the net; Be used for storage conveniently has access in the future.
Preferably, said wire communication also is connected with maintenance server on the net; Maintain easily grid.
Compared with prior art; Advantage of the present invention is: native system has been filled up the idle blank that is controlled at the ground county integral application in the area power grid of automatic voltage; Be over the ground under the county regulation and control integrated technique support platform improvement of voltage, idle work optimization control internal improve; Solved province,, the tactful interaction demand between the three grades of electric network models in county, inharmonic contradiction between strategy satisfies the idle requirement of higher level's electrical network to area power grid; The performance area power grid has also been realized ground county two-stage electric network reactive-load requirement of balance simultaneously to the supporting role of higher level's electrical network.
