When reactive power devices, whether capacitive or inductive, are purposefully added to a power network in order to produce a specific outcome, this is referred to as compensation. It’s as simple as that. This could involve greater transmission capacity, enhanced stability performance, and enhanced voltage profiles as well. . Series capacitors are utilized to neutralize part of the inductive reactanceof a power network. This is illustrated in Figure 2. From the phasor diagram in Figure 3 we can see that the load. . Shunt capacitors supply capacitive reactive power to the system at the point where they are connected, mainly to counteract the out-of-phase component of currentrequired by an. . A synchronous compensator is a synchronous motor running without a mechanical load. It can absorb or generate reactive power, depending on the level of excitation. When used. . Shunt reactor compensation is usually required under conditions that are the opposite of those requiring shunt capacitor compensation. This is illustrated in Figure 7. Shunt reactors may be. [pdf]
Such reactive power compensation devices are: The passive reactive power compensation includes the capacitor bank installation for reactive power injection. The active reactive power compensation consists of the use of flexible AC transmission system (FACTS) devices to change the reactive power and active power requirement.
However, after adding the dynamic reactive power compensation device SVC to the system, although the fall position was basically the same as above without the reactive power compensation device, the short circuit fault was removed.
The modal analysis method was used to find the optimal installation position for the reactive power compensation device. The improved particle swarm algorithm was used to optimize the capacity of the optimal reactive power compensation device to ensure the best performance of the compensation device.
Program 1: In the case that there is no reactive power compensation device in either wind farm when the active power is about 385 MW, the busbar voltage drops rapidly and quickly reaches the limit instability point. Program 2: When the SC-type capacitor bank is put in, it leads to a large oscillation of the wind turbine terminal voltage.
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.
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.
