Abstract

The invention provides a matrix exponent-based parallel calculation method for an electromagnetic transient simulation graphic processor. A to-be-researched overall electromagnetic transient simulation model of a power system is built under a state analysis framework; and electromagnetic transient rapid simulation of the power system is achieved by combining the data parallelism of a matrix exponent algorithm and the performance advantages of parallel calculation of the graphic processor. The matrix exponent-based parallel calculation method reserves good numerical precision and rigid processing capacity of a matrix exponential integration method, has general modeling and simulation capabilities of nonlinear links of power system elements, and achieves high efficiency of a matrix exponential integration algorithm in the field of large-scale electromagnetic transient simulation for the power system by high parallelism characteristic of data of the matrix exponent integration algorithm. Parallel calculation of the simulation graphic processor of the electromagnetic transient model of the general power system is achieved on the basis of the matrix exponential operation under a state analysis framework; and the calculation speed of the matrix exponent-based electromagnetic transient simulation method is improved.

Description

technical field

[0001] The invention relates to a parallel computing method for an electromagnetic transient simulation graphics processor. In particular, it relates to a matrix exponent-based electromagnetic transient simulation graphic processor parallel computing method suitable for power system electromagnetic transient modeling. Background technique

[0002] The electromagnetic transient simulation of the power system mainly reflects the change process of the electric quantity generated by the interaction between the electric field and the magnetic field in the system, and obtains the instantaneous value waveform of the three-phase voltage and current in the spectrum range from power frequency to tens of kHz, which requires detailed dynamic modeling. Only when the simulation step size of the module and microsecond level can be accurately described, the simulation scale of the system will be expanded and the amount of calculation will increase. At the same time, with th...
