Problems solved by technology

[0003] At present, the implementation station of the stability control system to ensure the safe and stable operation of the power grid is generally installed in a 220kV substation. In the actual implementation process, there are the following problems: 1) The object of removal is directly 110kV lines, and the granularity is large, so it is inevitable to cut off some important users; 2) Cut off After the 110kV load line, some 110kV stations with open-loop points will automatically restore power to the cut-off load through 110kV standby automatic switching or 10kV standby automatic switching, and lose the effect of load cutting

Embodiment Construction

[0027] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0028] Such as figure 1 As shown, the embodiment of the first aspect of the present invention proposes a stability control system, the stability control system includes a stability control master station 1, a stability control sub-station 2, and a stability control execution station 3 that are sequentially connected by communication;

[0029] The stability control master station 1 is used to perf...

Abstract

The invention discloses a stable control system and a load shedding method thereof. The stable control system comprises a stable control master station, a stable control substation and a stable control execution station, wherein the stable control master station, the stable control substation and the stable control execution station are in communication connection with each other successively. Thestable control master station is used for carrying out fault judgment in a 500kV power grid, and distributing required load shedding quantity to the subordinate 220kV stable control substation. The stable control substation is used for carrying out fault judgment in a 220kV power grid, distributing required load shedding quantity to the subordinate 110kV stable control execution station, and executing load shedding through a monitoring background after receiving a load shedding command of the superior 220kV stable control substation. The method is achieved based on the stable control system.According to the invention, load shedding objects are refined and reliability of implementation of load shedding measures is ensured.

Description

technical field [0001] The invention relates to the technical field of power system load control, in particular to a stability control system and a load shedding method thereof. Background technique [0002] With the development of the economy and the promotion of new energy applications, the interconnection of the power grid is becoming closer. Once the power supply channel fails, the power grid at the load end will be seriously insufficient. It is necessary to remove a large number of loads to ensure the safe and stable operation of the power grid. How to ensure the power supply of important and sensitive users is very critical. [0003] At present, the implementation station of the stability control system to ensure the safe and stable operation of the power grid is generally installed in a 220kV substation. In the actual implementation process, there are the following problems: 1) The object of removal is directly 110kV lines, and the granularity is large, so it is inevi...
