Abstract

The invention discloses an establishment method of an RTDS-EMS (real time digital simulator-energy management system) system-level closed-loop control experiment simulation platform. The method comprises the following steps: establishing a simulation model of an equivalent station on a real-time digital simulator RTDS system; performing real-time digital simulator RTDS simulation by utilizing the simulation model of the equivalent station; drawing an actual device wiring diagram corresponding to the equivalent station in an energy management system EMS; mounting a network communication interface card GTNET, configuring network running parameters of a front-end system FES; designing and developing a protocol converter to realize information intercommunication between the real-time digital simulator RTDS and the energy management system EMS; virtualizing a plurality of remote terminal units RTU, and controlling the connection between the virtual remote terminal unit RTU and the energy management system EMS to simulate inconsistent sampling time at different control centers in an actual electric network. The method realizes RTDS-EMS system-level closed-loop control.

Description

Technical field [0001] The invention belongs to the technical field of power system dispatching automation, and in particular relates to a method for building an RTDS-EMS system-level closed-loop control experiment simulation platform. Background technique [0002] The global shortage of energy resources and the large-scale development of power grids have prompted the emergence of new energy grid-connected power generation and various new algorithms. The use of these new technologies and new energies needs to be based on the safety and stability of the power grid. Therefore, network access detection for these new directions is currently an urgent problem to be solved, but direct research based on the actual system is bound to bring unpredictability to the operation of the power grid. Impact. In the debugging of the new algorithm, the simulation environment that is often used at present is offline. Although these simulation environments are effective for testing the feasibility o...
