Problems solved by technology

Load transfer is a common problem in regional power grid operation scheduling. When encountering equipment overload, equipment failure, power outage, equipment maintenance, in order to improve the reliability of power supply to users, dispatchers generally rely on dispatching experience or rough manual calculations , and then carry out load transfer and restore power supply to the lost load. Although the problem of restoring power supp

[0064] Terms and Definitions

[0065] Power point: Hot standby switch on the periphery of the de-energized area.

[0066] Transfer path: the sequence of actions of the switches.

[0067] Transfer capacity: the line load rate of the power point.

[0068] Network components: switches, units, loads, capacitors or reactors, transformers and lines are all network components. Among them, transformers, lines and switches are called double-ended components, and transformers and lines are also called series branches; units, loads, capacitors or reactors are called single-ended components, also called parallel branches.

[0069] Node: It is the connection point of network elements, and the elements are connected to form a grid through mutual common nodes.

[0070] Expert system definition: According to the historical operation experience of the power grid, define the load transfer strategy expert system.

[0071] Load group definition: According to the daily operation experience of ...

Abstract

The invention provides an assisted decision making method for load transfer in a regional power grid. The method comprises the following steps: (1) setting a target power-off device; (2) performing statistics on load information; (3) analyzing a load transfer strategy; and (4) evaluating economic safety. In the method, remote signalling, remote measuring and power grid topology information existing in a dispatching automation system are utilized fully to fastly and exactly generate a load transfer scheme capable of meeting the requirement of economic and safe operation of the power grid, thereby preventing the situations such as load shedding or long-time power off, out-of-limit overload and the like from happening during the load transfer scheme.

Description

technical field [0001] The invention belongs to the field of electric power automation, and in particular relates to an auxiliary decision-making method for regional power grid load transfer. Background technique [0002] Regional power grids are generally designed in a closed-loop mode, run in an open-loop mode, and are connected through a hot standby switch. The structure generally presents a radiation type. Load transfer is a common problem in regional power grid operation scheduling. When encountering equipment overload, equipment failure, power outage, equipment maintenance, in order to improve the reliability of power supply to users, dispatchers generally rely on dispatching experience or rough manual calculations , and then carry out load transfer and restore power supply to the lost load. Although the problem of restoring power supply to the lost load has been solved by experience, whether the transfer path is optimal, whether the transfer operation is simple, and w...
