Research on Medium Voltage Static pensator System
In the field of‘smart grid’,in intelligent electric transmission and distribution,custom power technologies,(STATic pensator)is the advanced plexed device in dynamic pensation. has nice performance in response speed, stabilized power voltage,reduced grid loss,increased transmitting capacity,limited of transient voltage improvement and reduced harmonic.
is the basic technology of the FACTS(Flexible AC Transmission System)by power electronics conversion,therefore based on the multiple pulse and multilevel converter’S topology research, of multilevel inverter for high power medium voltage applications is particularly order of the disquisition is the cascade multilevel inverter,multiple pulse converter,neutral point clamped(NPC)converter,hybrid multilevel converter,reactive current detection and auxiliary protection followings are the main work:
High power cascade is a typical nonlinear system,its control theory algorithm plex and to the dynamic math model of a active and reactive current for cascade ,a nonlinear dynamic control strategy for reactive power is this control method of two—input two-output linearization,the output variables decoupling control is the condition of occurring short circuit fault and high power load changing abruptly,the non
