To fulfill the dynamic requirements of the system, double loops control system with velocity stabilization loop and tracking loop is applied
為了實現系統的動態指標要求，確定採用含有速率穩定環和跟蹤環的雙迴路控制系統。 -
Aiming at the features of grid - connected pv system, a kind of grid - connected control strategy is presented, which is based on the multi - variable double - loop control and synchronization phase - locked control. the multi - variable double - loop control is used for the real - time tracking, and the inherent principle error existing in the single - loop control is eliminated. the synchronization phase - locked control makes the frequency and phase of output current equal to those of utility voltage
針對光伏並網的特點，本文提出了一種基於多變量雙環控制與同步鎖相控制的並網控制策略，多變量雙環控制用於電流的實時跟蹤，解決了只採用單環控制存在的原理性誤差問題；同步鎖相控制則保證輸出電流與電網電壓同頻和同相。 -
The simulation results show that our algorithm is effective in tracking the changing of channel without deep fading under the condition that transmission efficiency has been double compared with [ 113 ] with the same sub - carriers ; it is also effective to track the channel with deep fading under the condition that transmission efficiency has been increased obviously when linear precoded technology is used
模擬結果表明，當fir通道沒有深度衰落時，本文的演算法在相同的子載波和比[ 113 ]傳輸效率提高一倍的情況下，能有效地自動跟蹤通道的變化；當通道有深度衰落時採用線性預編碼的情況下，本文的演算法在比[ 113 ]傳輸效率有較大提高的情況下，也能有效地跟蹤通道的變化。 -
