Embodiment Construction

[0031] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0032] Method example:

[0033] The invention provides a method for simulating hardware task scheduling in a real-time simulation system. First, the hardware task to be simulated is split to obtain a corresponding number of subtasks; The running time of the subtasks; finally, the control program of the corresponding subtask is called in the simulation system to run according to the determined running time of each subtask. The number of the above-mentioned subtasks can be obtained by splitting the control and protection task function according to the execution cycle of the hardware task to be simulated and the simulation step size.

[0034] Specifically, the control and protection system is used as the hardware task to be simulated, such as figure 1 As shown, the scheduling method for simulating hardware tasks in the real-time simulation system o...

Abstract

The invention provides a method and device for simulating hardware task scheduling in a real-time simulation system. Firstly, the hardware task to be simulated is split; and then the running time of each subtask is determined according to the execution cycle of the hardware task and the simulation step length; Finally, according to the determined running time of each subtask, the control program of the corresponding subtask is called in the simulation system to run. For the modeling of complex hardware tasks in the real-time simulation system, it is ensured that the model can run in real time, and at the same time ensure that the model can accurately reflect the characteristics of the hardware task, and realize the real-time operation of the control and protection logic in the simulation system.

Description

technical field [0001] The invention belongs to the technical field of power system digital simulation, in particular to a method and device for simulating hardware task scheduling in a real-time simulation system. Background technique [0002] At present, more than 30 direct current transmission projects have been completed and put into operation in China, and the workload of operation and maintenance of direct current converter stations is increasing day by day. The DC control and protection system is the core of the entire secondary system of the converter station, with a large scale and complex logic. In the converter station, real-time closed-loop testing of the control and protection functions is impossible, which brings great safety risks to the operation and maintenance work and is not conducive to the safe and stable operation of the DC system. In order to improve the level of operation and maintenance and ensure the safe and stable operation of the DC project, it ...
