| 摘要: |
| 受仿真机存储容量及CPU处理能力的限制，其所能实时计算的电气节点数及存储容量都是有限的。随着电力系统建模日益复杂和完善，或系统的节点数超出了实时仿真器单个核的处理能力或所需存储容量太大，而给仿真器实时仿真大型电力系统带来了挑战。深入研究了结合状态空间和节点分析的仿真算法——State-Space Nodal(SSN)算法，将该算法应用到大型双馈风力发电系统，并通过RT-LAB实时仿真平台进行了仿真研究。仿真结果验证了SSN算法在实时化仿真多开关器件、大型电力系统的必要性和有效性。 |

| Abstract: |
| Simulator’s real-time calculation of the electrical nodes and storage capacity is limited by its hardware constraints. With the increasingly complex modeling of power system, when the electrical nodes are beyond the processing capacity of single core of real-time simulator or need a large storage capacity, the simulator will face a big challenge in simulating large power systems in real time. State-Space Nodal (SSN) method, a simulation method that combines state-space with nodal analysis, is applied to the large double-fed wind power generation system and simulated using RT-LAB. Simulation results verify the proposed SSN algorithm’s necessity and effectiveness in real-time simulation for large power systems, especially multi- switch networks. |
