Embodiment Construction

[0040] The specific implementation method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0041] Step 1: Derivation of the volt-ampere relationship of circuit components.

[0042] The basic solution methods of power system electromagnetic transient simulation problems can be divided into two categories: nodal analysis and state space analysis. Compared with the state variable analysis, the node analysis method has great advantages in terms of algorithm realization difficulty and simulation calculation speed, so the present invention selects the node analysis method as the solution method of the system. The invention divides the electromagnetic transient simulation system into a circuit element area, a calculation area, a storage area and a system control area.

[0043] To model and simulate a circuit component model, it is necessary to first obtain its volt-ampere curve, that is, the functiona...

Abstract

An erection method of an electromagnetic transient simulation system comprises the steps that modules of the electromagnetic transient simulation system are respectively zoned in a compute-intensive mode and a control-intensive mode, zones are achieved respectively according to the characteristics of the zones and packaged into IP, and finally the IP are allocated and calculated according to a power grid model required to be simulated by a user so as to erect the system. The erection method is short in development period, and the efficiency of iteration optimization or secondary development is high. Design can be directly performed by using software languages, and corresponding hardware description languages and RTL-level IP can be generated by comprehensively optimizing the languages and used for FPGA development. The flexibility of the system is improved, and the development period of the system is shortened.

Description

technical field [0001] The invention relates to a method for quickly realizing an electromagnetic transient simulation system, in particular to a method for designing and quickly realizing an electromagnetic transient simulation system based on a high-level synthesis tool. Background technique [0002] The electromagnetic transient simulation system can simulate the actual operation of the power grid, monitor the nodes in the power grid system, reproduce and analyze possible faults, and maintain the normal operation of the power grid. Real-time simulation is the basis for efficient power system stability analysis and online dynamic security assessment and control. The basic algorithm of electromagnetic transient simulation was proposed by Dommel et al. It was mainly used to study the overvoltage problem during the operation of the power system at first, and now a series of commercial electromagnetic transient simulation software has been produced. [0003] The dynamic frequ...
