Description
A kind of based on economizing the ground integrated road control method of drawing automatically.
Technical field
The invention belongs to the dispatching automation of electric power systems field, relate to a kind of based on economizing the ground integrated road control method of drawing automatically.
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 to regional dispatch and is drawn the instruction of appearance of a street amount; Regional dispatch is based on drawing road tagmeme table according to the accident of having formulated or rationing the power supply and draw road tagmeme table; Draw the road combination according to the real time data artificial nucleus to listing side by side, and draw back supply line's circuit breaker, the measure of stopping power supply by force by the power transformation monitor staff.
The main liaison mode that relies on of traditional power cuts to limit consumption operation; Notify the regional dispatch center by the provincial dispatcher of control centre; Assign the limited load task object, the 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; Arranging out needs the circuit of power cuts to limit consumption sequence, and 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.With manual operation is main, the information interaction difficulty between the province ground, and the statistics of the record that draws road and recovery time of circuit, the situation of drawing the road load, loss electric weight all need increase dispatcher's workload by dispatcher's artificial treatment greatly in addition.
2. intermediate link is many.As arrange circuit need the artificial nucleus to and calculate, the instruction of issue needs corresponding one by one different monitoring or the operations staff of electric substation to carry out, the whole execution flow process time is longer, can not realize the quick control load.
3. artificial winding displacement is complicated, lacks the aid decision means.Ground key degree is after the task of receiving; Rely on manual analysis fully,, lack effective aid decision means drawing dataway operation need to select contrast to draw the tagmeme table of rationing the power supply to combine current network load real time execution situation to confirm; Cause the poor efficiency of making a strategic decision, and have the possibility of mistuning degree, misoperation.
4. draw road efficient low.Carrying out multichannel when drawing the road; Lack effective closed-loop control means and measure; Draw road efficient on the low side, even the phenomenon on road occurs in time to draw, can't in time respond provincial scheduling requirement; Influence power network safety operation, the each department scheduling is at present all less than to drawing to ration the power supply effective management and technological means being provided.
