Каква е връзката между хармоничната компенсация и компенсацията на реактивната мощност?

При хармонично компенсация и компенсация на реактивната мощност компенсацията е всичко за компенсиране на реактивната мощност и двете са насочени към подобряване на коефициента на мощност .

Harmonic compensation also takes into account harmonic management. That is, in harmonic compensation, capacitors are also connected in series with reactors. Capacitors and reactors form a filter. At specific harmonic frequencies, series resonance occurs, and the impedance of specific harmonics is very low. Therefore, the harmonics in the system flow through the filter and no longer flow to the system connection point, achieving the effect of filtering harmonics. While reactive power compensation generally does not connect in series with reactors or only connects with 1%, 6%, or 12% of reactors. Its main purpose is to maintain capacitors and prevent harmonic overvoltage. It only generates reactive power and cannot filter. The difference is that if there are harmonics in the system and they exceed the standard, harmonic compensation usually needs to be installed. If the harmonics do not exceed the standard, conventional reactive power compensation can usually be used.

The low-voltage parallel power capacitors of Jinneng Electric are made by rolling metallized polypropylene film. They are processed with a special gold-plating process and have a cylindrical aluminum shell structure, which ensures the stability of performance and quality. In the power system, they can increase effective power, reduce reactive power loss, and perform reactive power compensation (used for Коригирайки коефициента на мощност на оборудването с ниско напрежение и подобряване на формата на вълната на напрежението), спестявайки енергия на мощността . В зависимост от различните случаи, те се разделят на еднофазни кондензатори и трифазни кондензатори; while the filter reactor adopts a technology specially developed for the harmonic filtering system, connected in series with the capacitors, it can perform reactive power compensation, effectively absorb grid harmonics, reduce losses, improve system power factor, enhance power quality, purify the grid, and ensure the safety of grid operation.
