Overload processing method

Abstract

The invention relates to an overload processing method. The method comprises the following steps of determining an overload line; establishing a bus domain which needs to be examined; establishing a transformer domain which needs to be examined; establishing an output set domain needing to rise; dividing a generator set in the output set domain needing to rise into generator set groups with different adjusting sensitivity grades; when an overload quantity satisfies a condition that delta L is greater than or equal to S1+S2+...+ Si+...+SK and is less than or equal to S1+S2+...+ Si+...+SK+SK+1, and the generator set group with a K+1th adjusting sensitivity grade to the generator set group with the highest adjusting sensitivity grade are in an overflow output state, determining whether the overload quantity is reduced to 0; when the overload quantity is reduced to 0, successively overflowing the output of the generator set groups whose adjusting sensitivity grades are greater than k, and calculating the at least required number of the overflow output generator set groups making the overload quantity be reduced to 0; and generating first prompt information. In the invention, minimum output rise amounts of the generator set group needing to be in an overflow state and the generator set group with a K+jth adjusting sensitivity grade are returned to scheduling personnel; the scheduling personnel carries out operation on the correlation generator set groups so as to eliminate the overload quantity and danger brought by equipment overload.

Description

technical field [0001] The invention relates to an overload processing method. Background technique [0002] When the power equipment in the power grid fails and trips, it may cause the relevant lines or transformers to be overloaded. When the lines and transformers are overloaded, dispatchers need to adjust the operation mode of related plants and stations in time to eliminate the overload, otherwise it will cause equipment damage and expand the impact of the accident. [0003] At present, dispatchers generally dispatch overload currents based on experience. This method requires dispatchers to have very rich work experience in order to carry out reasonable and accurate dispatching. Therefore, it is necessary to provide an auxiliary decision-making method to quickly deal with equipment overload, provide rich and accurate alarm information or prompt information for accident handling, and general dispatchers can dispatch according to the information to reduce or eliminate the...
