Problems solved by technology

[0006] Although the above-mentioned invention patent application describes a method for configuring the defense line of the high-cycle cutting machine, it does not involve how to structure the high-cycle related information collected by the stability control device (referred to as: the stability control device) with the high-frequency cut-off function. Combined with the real-time working conditions of the current power grid, the severable quantity is counted, and only the configuration principles of the high-cycle severing line of defense are discussed.

Abstract

The invention discloses a high circumference cutting machine line cuttable statistical method based on structured modeling. The method comprises the steps of acquiring a high circumference cutting machine line strategy included in an existing stability control device in a target area; analyzing the high circumference cutting machine line strategy, and obtaining basic elements required for modeling; according to the method of the structured modeling, based on the basic elements, establishing a high circumference machine line model covering a target area power grid; acquiring a cutting machine configuration scheme issued by a target area power grid regulation mechanism, according to the cutting machine configuration scheme and the high circumference cutting machine line model, counting the cuttable total amount of the high circumference cycles, and completing the counting of the cuttable amount of the high circumference cutting machine line. The cuttable total amount can be counted according to rounds and regions, the monitoring practical level of the stability control device is improved, and the ability of the power grid to resist risks is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of power system dispatching operation monitoring, and in particular relates to a severable statistical method for high cycle cutting machine defense lines based on structured modeling. Background technique [0002] With the increasing scale of new energy access and DC output capacity, the high-cycle risk of the power grid after the UHV DC block in the transmission grid is becoming more and more prominent. Serious consequences of disorderly disconnection of new energy sources and conventional power sources. In this context, as the third line of defense for power grid security and stability, the high-frequency cut-off line of defense is particularly important. In order to meet the needs of new energy consumption, the operation mode and output of thermal power units may change, which will lead to large changes in the high-cycle cut-off capacity during operation. It is necessary to realize real-time monitoring ...
