Embodiment Construction

[0044] The following is a preferred implementation case of the present invention, which includes the evaluation process of a daily maintenance plan preparation using the method of the present invention, and its characteristics, purposes and advantages can be seen from the description of the embodiment.

[0045] In the process of evaluating the daily maintenance plan, the evaluation is divided into 24 time periods. According to the order of time to be evaluated, the maintenance plan for each time period is sorted out. At the same time, the power flow data is integrated according to the obtained planning data and network topology data, and then according to the predetermined plan , operating limit constraints, etc. to automatically calculate the evaluation results until the evaluation of all time periods is completed.

[0046] The maintenance plan evaluation of the present invention mainly includes two parts, one is based on the evaluation of the power generation capacity loss, c...

Abstract

The invention belongs to the field of maintenance scheduling evaluation and optimization in the power system and relates to a maintenance scheduling safety evaluation method based on power generation loss and load supply adequacy. The method comprises the following steps: firstly integrating network topology data and planning data into flow data, extracting the missing data from the reference flow data to form complete flow, simultaneously carrying out sensitivity analysis based on network topology and computing the generating capacity loss and the load supply adequacy according to the results of sensitivity analysis and flow computation, wherein evaluation based on the generating capacity loss is to compute the sensitivity of a generator to all the branches by system network topology and compute the normalized value of the generating capacity loss according to the formula; and evaluation based on the load supply adequacy is to compute the adequacy of bus load supply according to the flow computation result, the sensitivity computation result and the branch operating limit restraint. The method solves the problems in the existing methods.

Description

technical field [0001] The invention belongs to the field of electric system maintenance plan evaluation and optimization, and relates to a method for safety evaluation of maintenance plan based on power generation loss and load supply adequacy. Background technique [0002] With the development of the power system, the scale of the power network is getting larger and larger, and there are more and more equipment under the jurisdiction of the dispatching center. All kinds of equipment have their own life cycles and need to be regularly scheduled for maintenance. In addition, due to infrastructure and technical transformation Necessary, it is necessary to arrange power outages of certain equipment from time to time. Power failure of equipment will cause changes in the operation mode of the power system, and may cause security problems in the power system, which in turn will affect the economic benefits of the power grid company. Therefore, it is of great significance to carr...
