In order to achieve the above object; the utility model comprises control and protection unit and some valve control unit; valve control unit monitors the operating state of some power models; control and protection unit exports to the control command of each valve control unit by high-speed serial bus, and valve control unit transmits the state information of each power model to control and protection unit by Ethernet.
Described control and protection unit, by performing the control command in control & protection strategy calculating chain type STATCOM, exports this control command to valve control unit.
Described valve control unit produces the pwm pulse for controlling power model according to the control command that control and protection unit exports and monitors the operating state of power model.
Described Ethernet adopts the MODUBUS agreement based on UDP.
Described control and protection unit is connected A phase valve control unit, B phase valve control unit and C phase valve control unit by high-speed serial bus with Ethernet.
Described control and protection unit to be connected A phase 1# valve control unit to A phase N# valve control unit, B phase 1# valve control unit to B phase N# valve control unit and C phase 1# valve control unit to C phase N# valve control unit by high-speed serial bus with Ethernet.
Compared with prior art, magnitude control of the present utility model can adjust according to the quantity of power model in working control object, and the magnitude control that the quantity when not changing other equipment in Control protection system by increasing or reduce valve control unit in Control protection system can change Control protection system makes original system meet the different needs of different control object power model quantity; The utility model can strengthen the flexibility of Control protection system greatly, reduces chain type STATCOM Control protection system R&D costs and R&D cycle.
Further, the utility model, can the power model of compatible different electric pressure by multiple valve control unit in parallel, strong adaptability.
Further, the utility model controls out of phase valve control unit by control and protection unit, and control precision is high, and flexibility is strong.
