摘　　要：随着新型电力系统的建设,电网的“双高”将显著影响电力系统的运行与稳定特性。因此提出了一种光伏并网稳控系统的标准化设计方案,包括组网通信架构、软硬件功能配置、出口方式设计和协调配合方法等,解决了目前光伏稳控出口仅能在“全站整切”或“全站整调”中人为二选一的局限性。该方案已成功应用于南方电网首个水光互补项目,RTDS仿真试验结果表明,所设计的稳控系统实现了功率快速精细化调节,通信延时短,通信组网可靠性高,能够适应实际电网的各种稳定性需求。With the construction of new power systems,the"double-high"characteristics of the power grid have a significant impact on its operation and stability characteristics.A standardized design solution for the stability control system of photovoltaic power station grid-connected is proposed,including network communication architecture,software and hardware functional configuration,export mode design and coordination methods.The solution addresses the current limitation where the export of photovoltaics stability control system can only be manually selected between"complete cut-off"or"complete adjustment."The effectiveness of the solution has been demonstrated through its successful implementation in the first hydro-photovoltaic complementary project in China Southern Power Grid.The results of RTDS simulation tests confirm that the designed stability control system enables precise adjustment of fast power modulation.It exhibits short communication delays and demonstrates high reliability in communication networking.Moreover,the system proves its adaptability to various stability requirements of actual power grids.
