Embodiment

[0136] The actual grid is tested in the smart grid dispatch control system. The test grid model is a network adjustment level grid, including: 865 plants, 1646 lines, 862 units, 2786 loads, 1386 transformers, 833 shunt capacitor reactors, 14 DC converters, circuit breakers / knife There are 35,705 brake workers. After topology analysis, the number of busbars is calculated to be 3446. The test environment is shown in Table 1:

Abstract

The invention provides a large power grid parallel network topology analyzing method. The method comprises the following steps that a smart power grid dispatcher control system power grid model is read, parallel verifying is carried out on the smart power grid dispatcher control system power grid model, and the large power grid parallel network topology is analyzed. According to the large power grid parallel network topology analyzing method, data of the power grid model are divided according to areas and stations, the topology searching function is packaged, parallel processing is carried out on the model data according to the different areas and the different stations, and accordingly parallel computation on the power grid topology analyzing is achieved. The result of the measurement on the actual power grid shows that the method has good stability and real-time performance, and the requirements for the topology analysis of the online system simulation, analysis and control application are met.

Description

technical field [0001] The invention relates to an analysis method, in particular to a large power grid parallel network topology analysis method. Background technique [0002] Network topology analysis forms the busbar-branch calculation model used in the online analysis and calculation of the power grid according to the physical connection relationship of the electrical components of the power grid and the opening / closing status of the circuit breaker / knife switch. The open / closed state of the switch and the withdrawn / restored state of the element form a bus model from the node model. The function is to analyze how many busbars are connected by the closed switch in a certain voltage level of a station, and the result is to divide the station into several busbars. System network analysis: analyze how many sub-networks (islands) the busbars of the entire power grid are connected by closed branches. Each subgrid is a collection of busbars with electrical connections, and the...
