摘要
根据超导储能装置（SMES）的工作原理，结合其结构特点与电路拓扑的发展趋势，建立了电压源型SMES相量模型。该模型将SMES等效为三相可控电流源，实现有功电流和无功电流独立控制，模拟SMES的功率响应特性，在功能上实现了对系统功率需求的准确跟踪，快速补偿系统的不平衡功率。最后，通过一个算例验证了SMES抑制单机无穷大系统功率振荡的效果，仿真结果表明该电压源型SMES可有效抑制系统的功率振荡，并使系统迅速恢复稳定运行状态，从而大大提高了系统的稳定性。
The voltage source-type SMES phasor model is established,combining with the structure characteristics and the development trend of circuit topology based on the working principle of SMES. The SMES is equivalent to three-phase controlled current source,and realizes the active and reactive-current control independently, and simulates the response characteristics of SMES. The SMES can accurately track the power demand of system and compensate the unbalanced power rapidly. Finally,the effect of SMES suppressing power oscillation of single-machine-infinite-bus system are presented using a simulation case, the results show that the voltage source-type SMES can effectively inhibit the power oscillation in the grid, and enables the system to restore the steady state quickly, as greatly improves the stability of power system.
