Abstract

The invention relates to a multi-time-scale hybrid real-time digital simulation system which comprises a controller, a protection system which sends a fault signal to the controller, a device level electromagnetic transient module, a component level switching transient module and a dynamic thermal process module. The controller sends a control command and a pulse signal to the device level electromagnetic transient module and sends a pulse signal to the component level switching transient module and sends a simulation output result to the device level electromagnetic transient module. The device level electromagnetic transient module sends the simulation output result to the controller. The component level switching transient module sends the over-voltage, over-current and fault state information of a device to the protection system. The dynamic thermal process module sends the temperature of a turn-off valve of the component level switching transient module to the protection system. The modules carry out data exchange orderly through an interface, and the combined simulation of electromagnetic transient, switching transient and thermal dynamic processes is realized. According to the technical scheme, a more comprehensive and real closed-loop physical testing environment is provided for the control and protection system.

Description

[0001] Technical field: [0002] The invention relates to the technical field of power electronics modeling and simulation, and more specifically relates to a multi-time scale mixed real-time digital simulation system. [0003] Background technique: [0004] As a new technical field in power electronics, the performance and reliability of power electronic devices based on turn-off devices have always attracted much attention, and detailed closed-loop physical testing of actual control and protection systems in advance is an essential step. The real-time digital simulation system realizes the controlled equipment and the power grid with digital models, and interacts with the actual controller in real time, so that the controller is equivalent to being connected to the actual application environment, so as to realize detailed simulation under complex operating conditions, disturbance or fault conditions. The closed-loop test fully verifies the function and performance of the cont...
