[0091] Network subdivision method for real-time simulation of complex power systems

[0092] 1) Use the depth-first search method to traverse the switching elements in the system

[0093] 1.1) Based on the system connectivity, the switching element nodes in the system are numbered from 1 to 148, a total of 148 switching nodes, starting from the switching node numbered 1, and giving the label number 1;

[0094] 1.2) Check that there is an unmarked switch node in the switch node numbered 1, that is, the switch node numbered 2, and give the node the smallest continuous mark number 2 that has not been used; take the node with mark number 2 as a new starting point , continue to look for the switch node with the label number 2 and there are unmarked switch nodes, that is, the switch nodes numbered 3 and 4. At this time, the node 3 with the smallest number value is given the smallest continuous label number 3 that is not used, and the above operations are repeated. ;

Abstract

The invention provides a real-time simulation network subdivision method for a complex power system. The method comprises the following steps: 1) traversing of system switch elements by adopting a depth-first search method; 2) subdivision of a subsystem based on switching node transfer; and 3) subdivision of an internal subnet of the sub-system based on proximity switch node combination. Hierarchical network subdivision is carried out according to subdivision of subsystems in the subdivision process and different subdivision targets of subnet subdivision processes in a single subsystem, and the problems that real-time simulation of a complex power system is difficult to achieve, and a traditional network subdivision method is low in subdivision efficiency, high in blindness and depends on the modeling experience of a designer are solved.

Description

technical field [0001] The invention relates to the field of real-time simulation of electric power systems, in particular to a real-time simulation network segmentation method of complex power systems. Background technique [0002] Efficient real-time simulation method is the key to realize real-time simulation of large-scale power system. In the process of real-time simulation, it is necessary to realize the real-time simulation of the electromagnetic transient state of the power system network topology with hundreds of nodes under the microsecond-level calculation step, which puts forward strict requirements on the rationality and efficiency of the system network division. The existing power system contains a large number of power electronic devices, and the components of these power electronic devices are unevenly distributed, resulting in low real-time calculation efficiency of the Rt-lab real-time simulation platform with switching components as the main factor affecti...
