Abstract

The invention discloses an automatic recognizing method for the multi-region dynamic running mode of a large power network. The method comprises the following steps: the state variables of active components contained in a node can be fast and reliably transmitted to a father node A in a regional power network by dint of optical fiber communication and successor nodes B1, B2, ellipsis, Bm in the regional power network; the running mode Gamma of the current system is obtain by carrying out online uniform discrimination according to a state recognition function Gamma which is equal to f (Beta0, Beta1, Beta2, ellipsis, Betam) after the father node A is combined with the state variables of the active components thereof. The method completely avoids the previous improper method which only can automatically recognize the running mode of certain specific power network, and can online-recognize the runner mode parameters of the current large power network dynamically and precisely; the recognition time of the method is short, and the recognition can be automatically finished within a few milliseconds; when the structure of the power network changes, the software of the node in the power network is not required to be redesigned, thereby the method greatly saves the labor resources, the material resources and the financial resources, and improves the automation degree and the efficiency; besides, the reliability is also improved.

Description

technical field [0001] The invention belongs to the technical field of electric power systems and automation thereof, and more precisely relates to a general automatic identification method for multi-area dynamic operation modes of large power grids. Background technique [0002] The scale of the power system is increasing day by day, the nodes in the power grid are expanding geometrically, and the connections between nodes are much more complicated than before. The previous automatic identification method is only for a specific grid. Once the grid structure changes, it is often necessary to redesign the software of the nodes in the grid. No matter in terms of manpower, material or financial resources, the previous method that can only automatically identify the operation mode of a specific power grid is not suitable. Therefore, there is an urgent need for a general-purpose method that can automatically identify the multi-regional dynamic operation mode of the large power g...
