摘　　要：异步互联调度优化可以保证背靠背直流输电系统的稳定运行,但不同调度时段会影响调度优化的均衡性和稳定性,由此,提出不同阶段的背靠背直流输电系统异步互联调度优化方法。在分析背靠背直流输电系统等值电路的基础上,根据整流器等值电路计算整流器输出的电压值,构建背靠背直流输电系统的出力模型;在发电阶段和电能输送阶段,设定异步互联调度的约束条件,设计直流输电系统异步互联调度优化算法,实现直流输电系统异步互联调度优化。实验结果表明,直流输电系统输出的功率始终稳定在20~42 kW,可以稳定提高均衡性和稳定性。The scheduling optimization of asynchronous interconnection can ensure the stable operation of the back-to-back DC transmission system,but different scheduling periods may affect the balance and stability of the scheduling optimization,hence,a scheduling optimization method for the asynchronous interconnection of the back-to-back DC transmission system in different stages is proposed.The equivalent circuit of the back-to-back DC transmission system is analyzed,and the voltage value output by the rectifier is calculated according to the equivalent circuit of the rectifier,and the output model of the back-to-back DC transmission system is constructed.In power generation and transmission stage,the asynchronous interconnection scheduling constraints and optimization algorithm of DC transmission system are designed,and the asynchronous interconnection scheduling optimization of DC transmission system is realized.The experimental results show that the output power of the DC transmission system is always stable between 20 kW and 42 kW,which can stably improve the balance and stability.
