Embodiment Construction

[0018] like figure 1 As shown, the method for obtaining the real-time status of the grid components of the present invention includes the following steps:

[0019] (1) Obtain data from the energy management system. The obtained data includes: the name of the plant station, the name of the line and the node numbers at both ends of the line, the name of the switch and the node numbers at both ends of the switch, the name of the switch and the nodes at both ends of the switch No., name of transformer and node numbers at both ends of transformer, name of generator and node number of generator, name of busbar and node number of busbar, running / non-running state of switch and switch;

[0020] (2) Select the first switch;

[0021] (3) Traversing all switches to determine whether the name of the switch is divided by 10 and then taken as an integer to be the same as the name of the current switch;

[0022] (4) If the name of the knife switch is divided by 10 and then rounded, it is t...

Abstract

The invention provides a method for acquiring real-time states of a power grid element and belongs to the technical field of relay protection of power systems. The method comprises the following steps of: firstly, acquiring data from an energy management system; secondly, reducing the scale of a power grid by using an idea of fusing nodes; and finally, forming an adjacency list of all nodes of the power gird, analyzing the connectivity of power plants and power stations, and judging operating / non-operating states of the element. According to the method, the real-time states of the power grid can be fast acquired, the interface of a power grid online checking system and the energy management system is realized, and the speed of acquiring the real-time states is improved.

Description

technical field [0001] The invention belongs to the technical field of electric power system relay protection, and in particular relates to a method for acquiring real-time states of power grid components. Background technique [0002] How to quickly and accurately obtain the real-time status of grid components from the energy management system has become one of the urgent problems to be solved in the grid online system. At present, many scholars have studied the related issues of real-time state acquisition of power grid components, but they have not studied the overall structure and implementation methods of real-time state acquisition in depth, avoiding key technologies such as data acquisition, scale reduction, and topology analysis in real-time state rapid acquisition. question. Contents of the invention [0003] The purpose of the present invention is to provide a method for obtaining the real-time status of power grid components, which can solve several key technic...
