为了维护电力系统的正常运行,需要用到电网仿真技术对电网中的节点进行实时监测.软件仿真灵活性高但仿真步长较大,达不到实时性要求;基于FPGA (Field Programmable GateArray)实现的硬件仿真系统,其仿真步长小但灵活性差,开发效率低.由此提出一种基于HLS(High-Level Synthesis)实现的电磁暂态仿真系统,既兼顾了软件仿真的灵活性,又能在FPGA上实现小步长仿真,且相对于目前大部分FPGA电磁暂态仿真系统,性能提升约30％,开发周期显著降低,二次开发效率明显提高.%The grid simulation technology monitoring the nodes in the power grid real time is used to maintain the normal operation of the power system.Software simulation is flexible while the simulation step is large so it's hard to meet the real-time requirements.The hardware simulation system which is based on FPGA (Field Programmable Gate Array) gets the small simulation step while it's inflexible and the development efficiency of it is very low.This paper presents a HLS (High-Level Synthesis) implementation of the electromagnetic transient simulation system which is flexible and gets low simulation step and compared with most of the current FPGA electromagnetic transient simulation system,the performance is improved by about 30％,the system development life cycle is significantly reduced and the secondary development efficiency improved significantly.
