Problems solved by technology

[0006] The above-mentioned (1) type of grid reconfiguration method directly disentangles the electromagnetic ring network will reduce the reliability of power grid power supply. (2) type of grid reconfiguration method depends on the operation of the dispatcher and cannot be realized automatically. (3) type of transmission network Reconfiguration relies on automatic control devices, which requires increased grid investment and construction costs. Generally, a fixed construction period is required, and the application is not flexible enough

Abstract

The invention discloses a transmission network dynamic reconfiguration method based on a 3 / 2 wiring mode. The transmission network dynamic reconfiguration method comprises the steps of: constructing atopological structure and parameter model of a power grid real-time mode or a mode to be studied, and evaluating capability and risks of independent district-wide operation of district power grids ofinterest; evaluating benefits and potential risks of electromagnetic looped network operation formed by the district power grids, and analyzing a cost of solving the electromagnetic looped network risks; analyzing a 3 / 2 wiring string configuration method in a transformer substation, and providing a dynamic reconstruction scheme for solving the electromagnetic looped network risk problem; and considering power supply reliability of a normal mode and potential risks of an accident mode, and deciding a district power grid operation mode optimal arrangement scheme and a power grid dynamic reconfiguration suggestion comprehensively. The transmission network dynamic reconfiguration method based on the 3 / 2 wiring mode avoids the load flow from shifting within the electromagnetic looped network in the accident mode, does not cause overload of low-voltage level equipment or damage to the system stability, and improves the operation safety of the system.

Description

technical field [0001] The invention relates to the field of power system operation analysis and control, and more specifically, relates to a dynamic reconfiguration method of a power transmission network based on a 3 / 2 connection mode. Background technique [0002] Power grid reconfiguration refers to reorganizing the topology of the power grid by changing the on-off status of line switches / knife switches and bus tie switches to achieve network topology adjustments that meet specific operating requirements. At present, power grid reconfiguration is widely used in the distribution network, achieving the goals of balanced load distribution, improved power supply reliability, and reduced network loss. [0003] In the transmission network, the planned grid structure is usually used to maintain full wiring operation, but with the continuous strengthening of the grid structure, problems such as short-circuit current exceeding the standard and electromagnetic ring network operatio...
