Problems solved by technology

[0004] However, the real-time computing performance and simulatable scale of the real-time simulator depend on the computing power of the target machine. The smaller the simulation step size, the greater the calculation pressure, and the smaller the real-time simulation scale
With the increasing demand for power system simulation scale, it is increasingly difficult for a single real-time simulator to meet the real-time and scale requirements of simulation.

Abstract

The invention provides a multi-simulator joint simulation method and system. After the current time step is started and the first receiving register of the first simulator obtains the first numerical value, the next action is carried out, and the second numerical value in the first sending register is transmitted to the second receiving register of the second simulator, so that the synchronization of the simulation time steps of the two simulators is realized. A first numerical value is limited to be used for simulation calculation of the first simulator at the current time step, a second numerical value is limited to be used for simulation calculation of the second simulator at the next time step, and the delay time for the first simulator to obtain the first numerical value and the delay time for the second simulator to obtain the second numerical value are fixed respectively, so that the transmission line decoupling joint simulation algorithm is ensured to be effective.

Description

technical field [0001] The present application relates to the field of simulation, in particular, to a multi-simulator co-simulation method and system. Background technique [0002] With the continuous improvement of national electricity demand and the scale of modern power systems becoming larger and larger, a large number of power electronic equipment such as wind / solar / storage and other renewable energy generation equipment, high-voltage direct current transmission equipment, and micro-grid equipment are connected. to the power grid, making the power grid operating characteristics and control characteristics present strong nonlinear characteristics. In order to realize the accurate analysis of the "power electronics" power system, it is necessary to simulate and reproduce it accurately by means of analog or digital methods. [0003] With the development of computer technology, digital power system simulation method has been widely used in power system simulation and anal...
