Problems solved by technology

[0003] When generating the outage plan, various constraints of the current power system and the outage window period of the equipment will be considered; too many constraints may lead to the inability to obtain the optimal outage plan result; at this time, the dispatcher can only make a decision on the calculation data based on experience. Judgment and repeated adjustment of data; this traditional manual adjustment method based on experience is inefficient, labor-intensive, and the adjustment effect is not obvious
[0004] Aiming at the time-consuming and labor-intensive and ineffective problem of manually adjusting the constraints in the blackout plan, no effective solution has been proposed so far.

Abstract

The invention provides an adjusting method and apparatus for constrained condition of power-off plan. The method comprises: obtaining a power-off device to be planned and the power-off window period and the constrained condition of the power-off device; according to the power-off window period and the constrained condition, determining whether it is possible to obtain the convergence result of the power-off plan; if it is not possible to obtain the convergence result, calculating to obtain the importance indicators of the power-off device corresponding to the power-off window period and the constrained condition based on preset importance coefficients and weight coefficients wherein the importance coefficients include a standard power-off maintenance cycle importance coefficient, a voltage level importance coefficient and a load rate importance coefficient; and according to the importance indicators and the preset adjustment variables, adjusting the power-off window period and / or the constrained condition until the convergence result of the power-off plan is obtained. The adjusting method and apparatus of the invention reduces the workload of maintenance workers to adjust the constrained condition and the power-off window period of a power-off plan, therefore, increasing the adjusting efficiency.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and device for adjusting constraint conditions in a power outage plan. Background technique [0002] The power outage plan is to reasonably arrange relevant equipment for power outage maintenance within the maintenance cycle of power transmission equipment, so as to ensure the normal operation of power transmission equipment, ensure the safety of power transmission in the power grid, and meet the transmission capacity requirements of the power grid. The maintenance and outage of equipment will have an important impact on the reliability of the system. Arranging power outages for equipment in a planned way can find internal problems that cannot be found by conventional tests and external observations, and timely discover and deal with hidden dangers of equipment, which is very important for improving the reliability of power system operation. has a very important ...
