Compensator

automatically adjust the size and nature (capacitive or inductive) of output reactive power according to the load characteristics and working conditions. Therefore, in essence, the 10kV power quality compensator can be equivalent to a capacitor or reactor in the same size which can be continuously adjusted. converter, has realized the qualitative leap of reactive power compensation method. It is no longer using capacitance and inductance components of large capacity, but through the high frequency switching of the large power electronic devices to achieve the reactive energy transformation. Technically speaking, 10kV power quality comprehensive compensator has the following advantages compared with the traditional reactive power compensation device: (1) Faster response time Response time of 10kV power quality comprehensive compensator: 5ms. Response time of the traditional dynamic compensation device is not less than 50ms. The 10kV power quality comprehensive compensator can be mutually transformed in a very short period of time, from rated capacitive reactive power to rated inductive reactive power. The incomparable response speed is totally enough to compensate for the impact load. (2) Stronger ability to suppress voltage flicker The traditional dynamic compensation to suppress voltage flicker can be up to 2:1, while the 10kV power quality comprehensive compensator can reach 5:1, or even higher. In addition, due to the fast response of the 10kV power quality comprehensive compensator, enlarge the device capacity can continue to improve the ability to suppress voltage flicker.
