【摘要】 为评估对灵宝背靠背直流联网工程直流系统控制保护技术的掌握情况并保证工程进度按计划顺利实施,在现场调试前对二次系统设备依设计规范在实验室进行了闭环仿现场运行试验。采用北京网联公司(BDCC)实时数字仿真器(RTDS)建立了仿现场一次试验回路模型,同时根据直流输电基本调节原理建立了使试验模型仿真运行所必须的RTDS软件内部换流器控制模型,以校核模型运行的仿真度。在内部模型的控制下RTDS试验回路模型的结构参数被调整到其所有运行状态变量均与设计值相符合,证明了试验模型仿现场运行的有效性。经过校核的RTDS试验回路已成功地应用于灵宝工程整套二次设备的功能验证。更多还原

【Abstract】 Lingbao BTB converter station is the first HVDC engineering in which the technology & equipments are all made in China.For the taking a view of the mastery of control-protection technique as well as ensuring engineering rate on schedule,State Grid Corporation requires to carry a loop simulation for secondary equipments before on-site commissioning.Simulation circuit is set up by BDCC with RTDS.At the same time,it is absolutely necessary for checking simulation and validating its confidence that developing a RTDS converter control model based on HVDC control theory as internal controller.With the internal controller,simulation circuit model is adjusted so as to the every variable accord with design values.Accredited RTDS simulation circuit has been successfully used for the function-verifications test of HVDC control & protection equipments.更多还原
