Description
A kind of based on economizing the ground integrated road control method of automatically drawing.
Technical field
The invention belongs to dispatching automation of electric power systems field, relate to a kind of based on economizing the ground integrated road control method of automatically drawing.
background technology
Power cuts to limit consumption refer to electrical network have an accident or the uneven situation of power supply and demand under, provincial scheduling is assigned and is drawn the instruction of appearance of a street amount to regional dispatch, regional dispatch is based on drawing road tagmeme table or ration the power supply and draw road tagmeme table according to the accident having made, draw road combination according to real time data artificial nucleus to listing side by side, and pull open supply line's circuit breaker by power transformation monitor staff, the measure of stopping power supply by force.
The main liaison mode that relies on of traditional power cuts to limit consumption operation, notify regional dispatch center by the provincial dispatcher of control centre, assign limited load task object, regional dispatch personnel are again according to current operation of power networks situation, in conjunction with drawing the tagmeme table of rationing the power supply, arrange out and need the circuit of power cuts to limit consumption sequence, and the corresponding monitoring of notice or the operations staff of electric substation execution.This pattern exists following obvious deficiency:
1. automaticity is low, lacks workflow management.Take manual operation as main, the information interaction difficulty between province ground, in addition the record of circuit La road and recovery time, draw road load situation, lose electric quantitative statistics and all need to, by dispatcher's artificial treatment, greatly increase dispatcher's workload.
2. intermediate link is many.As arrange circuit need artificial nucleus to and calculate, the instruction of issue needs corresponding different monitoring one by one or the operations staff of electric substation to carry out, whole execution flow time is longer, can not realize quick control overhead.
3. artificial winding displacement complexity, lacks aid decision means.Ground key degree is receiving after task, rely on manual analysis completely, draw dataway operation select on need contrast draw ration the power supply tagmeme table in conjunction with current network load real time execution situation determine, lack effective aid decision means, cause decision-making poor efficiency, and have the possibility of mistuning degree, misoperation.
4.La road efficiency is low.Carrying out multichannel while drawing road, lack effective closed-loop control means and measure, draw road efficiency on the low side, even there is drawing in time the phenomenon on road, cannot respond in time the demand of provincial scheduling, affect power network safety operation, dispatch at present all less than providing effective management and technological means for drawing to ration the power supply each department.
