For S band rotary joint,VSWR is less than 1.2 over the frequency range from 1.2GHz to 4.4GHz. For P band rotary joint,the structure of the reentrant resonator is used to reduce the length of the rotary joint to aboutλ/4, and the special and small size requirement is satisfied.展开更多
针对宁夏电网自动发电控制(Automatic Generation Control,AGC)方式单一的问题,对目前的AGC控制策略进行优化。将单一的区域偏差控制(Area Control Error,ACE)划分为多区域多目标控制,主控制区主要以联络线ACE为主,分控制区在断面稳定...针对宁夏电网自动发电控制(Automatic Generation Control,AGC)方式单一的问题,对目前的AGC控制策略进行优化。将单一的区域偏差控制(Area Control Error,ACE)划分为多区域多目标控制,主控制区主要以联络线ACE为主,分控制区在断面稳定裕度较大时以主控制区控制目标为主,在断面稳定裕度较小时以断面稳定控制为目标。优化结果表明:AGC优化策略能将稳定断面和联络线交换功率控制在合格范围内,达到了宁夏电网AGC目标。展开更多
