Renovation location: FAW forging workshop low-voltage power distribution Renovation unit: Zhejiang Yide Technology Co., Ltd.        Transformer: 5600KVA     Original power factor: around 0.7, target: above 0.95     Load: 3 intermediate frequency furnaces     Power: 3 intermediate frequency furnace power is 90KW

Recently, the YD-8CKH controller produced by the company has passed the “CQC” certification of China's national compulsory product, and recently obtained the “CQC” certificate and the approval for the use of the mark.

The transformer capacity is 100KVA, the transformer is changed, and the load is mainly used by residents. This equipment mainly solves the three-phase load imbalance, and also solves the reactive power compensation, the bidirectional fast adjustment of reactive power, and the stable system voltage in real time.

The transformer is a public transformer with a capacity of 315KVA. The load is mainly for residential electricity, single-phase load such as lighting, air conditioning, heating, etc., and there is a long-term three-phase load imbalance.

Chain factory SVG reactive power compensation comprehensive solution

The three-phase voltage source of a three-phase balanced circuit must be a sine wave with the same frequency, the same amplitude, and 120 degrees difference in phase; the three-phase load impedance is the same and both are linear impedances, so the three-phase currents are all sine waves. And the frequency is the same, the amplitude is the same, and the phases are 120 degrees out of each other. Absolute three-phase balance does not exist, and the actual three-phase system always has different degrees of imbalance. The grid hopes that the three-phase current of the user load will be balanced as much as possible. Otherwise, the three-phase unbalanced current will cause the transformer capacity to be wasted and the neutral current to be too large. The grid hopes that the reactive current of the user load is as small as possible, otherwise the reactive power is in the grid. Circulating back and forth with the load, resulting in wasted power; the grid hopes that the harmonic current of the user load is as small as possible, otherwise the harmonics will cause the grid voltage and current to be distorted, causing the equipment to work abnormally; the user wants the voltage amplitude provided by the grid to be more stable. Well, otherwise too high or too low voltage will cause equipment protection or even damage.
