Abstract

The invention discloses an FCB set distribution method. The method comprises the following steps: obtaining an electrical network data file, and rejecting error data in the file; according to the file, searching for a largest electrical island, and determining a target electrical network; generating a topology structure diagram corresponding to the target electrical network; traversing various feasible FCB set distribution positions by use of a recurrence method, and solving optimal distribution positions respectively corresponding to various distribution numbers; respectively calculating economic indicators corresponding to the various optimal distribution positions; and determining a final FCB set distribution position, and performing distribution. In the method brought forward by the invention, the economic indicators are combined, and the characteristics of investment cost and economic benefits are taken into consideration so that the disadvantage of over high computational complexity is overcome, the robustness is high, and an FCB set optimal distribution scheme can be rapidly determined. The method can shorten calculating frequency and calculating time, and the obtained FCB set distribution scheme can simultaneously satisfy the requirements for economic benefits and safety.

Description

technical field [0001] The invention relates to the technical field of safe operation of electric power systems, in particular to a point layout method for FCB units. Background technique [0002] At present, the power grid has formed multiple ultra-high-voltage AC and DC "west-to-east power transmission" channels, and the transmission capacity and actual power transmission scale both exceed 1,000MW, making it one of the most complex AC-DC hybrid power grids in the world. However, with the increase in the complexity of the power grid, the existence of multi-feeder DC transmission and the increasing load, the margin for stable operation of the power grid is gradually reduced, the reactive power supporting capacity of the receiving end network is insufficient, and the system damping is relatively weak. Severe failures such as multiple complex failures, loss of large power supply at the receiving end, or refusal or malfunction of important line safety automatic devices may caus...
