Description

An Active Power Filter with SVG Function

technical field

The utility model relates to the field of active power filters, in particular to an active power filter with SVG function.

Background technique

SVG is a static var generator, also known as a static synchronous compensator, which has the purpose of making the circuit absorb or send out reactive current that meets the requirements to achieve power reactive power compensation. The active power filter is a new type of power electronic device used to dynamically suppress harmonics and compensate reactive power. It can quickly track and compensate harmonics of different sizes and frequencies. The reason why it is called active is relative to Passive LC filters can only passively absorb harmonics of fixed frequency and size. APF can control and actively output the size, frequency and phase of the current by sampling the load current and separating the harmonics and reactive power. And it responds quickly, offsets the corresponding current in the load, realizes dynamic tracking compensation, and can not only compensate harmonics but also compensate reactive power and unbalance.

The existing active power filter dissipates heat by providing heat dissipation holes on the front surface, and prevents dust from entering the filter through the dust-proof net provided, but the walls of the heat dissipation holes and the dust-proof net are easy to accumulate during use Dust, with the use of the filter, the dust will gradually accumulate on the wall of the cooling hole and the dust-proof net. As long as there is dust accumulated on the dust-proof net and the wall of the cooling hole, it will affect the circulation of the air and affect the heat dissipation of the filter. Some filters cannot remove the accumulated dust accumulated on the dust filter and cooling hole walls in real time. Usually, after a period of time, the staff will take out the dust filter to clean the accumulated dust, but at this time the dust has already accumulated in the dust filter. The mesh and the wall of the heat dissipation hole affect the internal heat dissipation efficiency of the filter, which is not conducive to the long-term use of the filter.
