For two H bridge tandem workings.According to above-mentioned hypothesis ULVector is constant, works as Um2When the DC bus-bar voltage of power module is relatively low,
Um2Upper superposition and current direction active voltage vectors Δ U in the same direction, then power module absorbs active from power grid, improves DC bus
To reference value；Work as Um2When the DC bus-bar voltage of power module is higher, in Um2Upper superposition and the reversed active voltage of current direction
Vector Δ U, then power module discharges active to power grid, reduces DC bus to reference value.The total voltage vector of phase is constant, between grade
DC bus-bar voltage balance control does not interfere with overall DC bus-bar voltage balance control and alternate DC bus-bar voltage balance
Control.When SVG is operated normally, power module always absorbs active power from power grid, therefore superposition amount Δ U is limited in by table
Show the circle of dotted line of module voltage adjustable range and the closed area of module voltage and electric current vertical line composition.And so on, this mutually its
The DC bus balance control vector of its power module is as shown in Figure 6 b.
It please refers to shown in Fig. 7, the DC bus-bar voltage regulated quantity of single power module is as follows:
Wherein, the product of locking phase angle sine and current properties (direction) sign function is equivalent to unitary current instantaneous value, with
Network voltage is in 90 °, this is because very little is lost in SVG, δ ≈ 0 ignores the phase angular displacement of output voltage generation.
It is illustrated by taking 10kV SVG as an example below, wherein IGBT selects 1700V model, and capacitor selects 1200V model, directly
Stream busbar voltage average value is set as 1000V, and voltage fluctuation is controlled in 200V by hardware and software means.Then each power
Module output AC voltage virtual value isEvery phase converting link minimum series isTherefore every
Phase converting link takes 9 grades, more obvious than 12 grades of existing every phase converting link few.6kV is similar with the calculation method of 35kV, can incite somebody to action
6kVSVG series is down to 5 grades, 35kVSVG series can be down to 32 grades, therefore not to repeat here.
The control method of the static reactive generator of the embodiment of the present application, by raising the setting value of DC bus-bar voltage,
