What are Reactive Power and Reactive Power compensation？ Reactive power is a key part of AC electrical systems—it''s the energy that flows back and forth between the power source and the load. Unlike active power, which does the actual work like powering lights or running machines, reactive power doesn''t directly get used up. But it plays a crucial role in

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.
Reactive power is either generated or consumed in almost every component of the system. Reactive power compensation is defined as the management of reactive power to improve the performance of AC systems. Why reactive power compensation is required? 1. To maintain the voltage profile 2. To reduce the equipment loading 3. To reduce the losses 4.
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.
