Program 1: The program of the reactive power compensation device, SVC, and a combination of SVC and parallel capacitors are used. The system has a three-phase short-circuit fault in the middle part of the transmission line between the busbar and the grid-connected busbar at 2.5 s, and the fault is eliminated after 0.3 s resection.
With the increasing proportion of wind power access year by year, it brings many challenges to the voltage stability of power systems. In order to maintain the stability of the voltage in the power grid, it is impossible to take into account the regulation ability and economy when a single reactive power compensation device is installed.
The cost advantage of the device itself, compared with the SVC type, is that the SVG type reactive power compensation device adopts digital control technology, which has high system reliability, basically does not need maintenance, and can save a lot of maintenance costs.
In summary, the voltage support ability of the above six reactive power compensation configuration programs is enhanced in turn. The minimum is when the active power of program 1 is about 385 MW, and the bus voltage drops rapidly. The maximum is when the active power output of program 6 reaches 610 MW, and the voltage instability finally occurs.
Related scholars proposed that in the process of voltage static stability research, the corresponding reactive power compensation device should be added to the weak point of voltage, which can basically meet the requirements of wind power delivery in the Hami area to a certain extent.
The active power margin and modal numerical analysis of the wind power gathering area in the Hami area show that the Mahuanggou east wind farm, located in the Santanghu wind area, is the weak node of voltage in this area, so this area is the best place to install reactive power compensation devices.
