定时滞 meaning in English

definite-time lag
fixed time lag

The validity and superiority of all these are proved by use the parallel converter of novel upfc to implement reactive current compensation , zero sequence and negative sequence currents compensation , harmonic currents compensation and the mixed compensation of them . this thesis also studies that use novel upfc to implement two phases operating in high - voltage transmission lines by theory analyze and simulation testify
提出了基于多电平变换器的广义大功率有害电流补偿的概念，提出了适合于它的多环定时滞环控制方案，通过用新型upfc的并联变换器实现无功补偿、零序和负序补偿、谐波补偿及它们的综合补偿来验证了其有效性和优越性。
