Low-frequency load-decreasing data intelligent generating method based on power grid dispatching technology

Abstract

The invention provides a low-frequency load-decreasing data intelligent generating method based on a power grid dispatching technology. The intelligent generating method is characterized in that invalid load information of low-frequency load-decreasing data historically stored in a database can be alerted and deleted by a low-frequency load-decreasing generating tool on a D5000 system work station, corresponding turns of calculating methods can be generated by manufacturing formworks, calculation is performed, and calculation results are written into the database. The method disclosed by the invention utilizes a more concise and visual display interface to define low-frequency load-decreasing data information, automatically calls the corresponding turns of generated calculation methods to calculate, meanwhile can make statistics on, display and compare the low-frequency load-decreasing historical information and improve automatic management level and efficiency of power grid dispatching.

Description

technical field [0001] The invention relates to a method for intelligently generating low-frequency load-shedding data, in particular to a method for intelligently generating low-frequency load-shedding data based on power grid dispatching technology, which belongs to the field of power system automation. Background technique [0002] Low-frequency load shedding means that when the frequency of the power system drops due to a gap between the demand for power generation and power loads, according to the preset action frequency value, a part of the pre-arranged secondary loads in the system will be removed in turn, so that the system The active power domains are rebalanced and the frequency is ramped up until the demands of generating and consuming loads are balanced. [0003] With the stable and mature application of the EMS system and the promotion of the concept of the model center, it is possible to establish the intelligent generation of low-frequency load shedding data o...

Problems solved by technology

[0004] At present, the power supply companies in various cities mainly write the low-frequency load shedding data information into the database through the formula definition. Although the maintenance function of the low-frequency load shedding information of the plant and station can be realized, when the data round information changes, it needs to be manually searched and changed, and the maintenance workload Large, and does not have the function of quickly querying low-frequency load shedding information by responsibility area and round, and cannot perform historical round information comparison, which seriously affects the automation level of the power system and the work efficiency of maintenance personnel
