分址级联特高压直流输电系统相较于常规两端特高压直流输电系统在接线方式和回线转换方面更加灵活和复杂。文中基于实际送端分址级联特高压直流工程,设计了直流系统接地方式转换策略,从而满足送端低压换流站灵活投退的应用需求。针对接地方式在大地回线和金属回线运行方式下可能存在的转换失败问题,分别提出了小电流阶跃和受端换流站短时接地的应对策略。基于实际控制保护装置与实时数字仿真的试验验证了所提控制策略的有效性。
The site-division cascaded ultra-high voltage direct current (UHVDC) transmission system exhibits greater flexibility and complexity in connection configurations and return circuit transfer compared to conventional two-terminal UHVDC transmission systems. Based on an actual sending-end site-division cascaded UHVDC project
this paper designs a transfer strategy for the grounding modes of DC system
which satisfies the requirements for flexible commissioning and decommissioning of the sending-end low-voltage converter station. To address potential grounding mode transfer failures during ground return and metallic return operation modes
this paper proposes countermeasures involving small current step injection and short-term grounding of the receiving-end converter station
respectively. The effectiveness of the proposed control strategy is validated through experiments utilizing actual control and protection devices in conjunction with real-time digital simulation.
