Embodiment Construction

[0035]In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0036] In order to transmit information such as data and control, the power system is usually connected with a communication system. In the traditional power system simulation process, the impact of the communication system on the power system is not considered or considered offline, resulting in low authenticity and accuracy of the simula...

Abstract

The invention discloses a method for synchronous control based on joint simulation of a power system and a communication system. The method comprises the following steps of after a basic time step length is entered, judging if the current time contains a decision event or not; if the current time contains the decision event, sending the original collection data of a simulation system of the power system to a simulation system of the communication system; after the returned collection data for decision is received, carrying out decision calculation according to the collection data for decision and historical command data, to generate a decision calculation result; judging if the result contains an operation command to be sent or not; if the result contains an operation command to be sent, sending to the communication system; after the returned executable operation command is received, inserting into a joint simulation time axis in a way of a command sending event; and when the command sending event exists in the basic time step length, adjusting the equipment state of the power system according to the executable operation command. The invention also provides a device for the synchronous control. The problem of synchronous control in the simulation of the two systems is solved.

Description

technical field [0001] The present application relates to the technical field of electric power system, in particular to a synchronous control method and device based on joint simulation of electric power system and communication system. Background technique [0002] The power grid system plays a pivotal role in today's rapid development, and its stability and security will have a major impact on the smooth operation of the economy and society. In order to accurately evaluate and analyze the stability and security of the power grid system, pre-simulation is usually required, especially with the development of the smart grid, the real-time interaction of information based on the power system and communication system has become an important factor affecting power system control, protection and other functions. In the case of important factors, the power system simulation problem is particularly prominent. However, the prior art either does not consider the influence of the co...
