Ningxia Nongken dairy factory power distribution quality solution

1. Industry overview

Ningxia Farming Dairy Co., Ltd. is a wholly-owned subsidiary of Ningxia Farming Group. Dairy production equipment is a precision instrument, which requires high stability of power grid. The fluctuation of power grid voltage is relatively large, and these fluctuations will seriously affect the normal operation and service life of electrical equipment, and will also affect the quality of products.

2. There are problems

1) A large number of photovoltaic, wind and other new energy connected to the grid, so that the operation mode of the power network changes, causing power distribution and grid impedance changes.

2) The power load changes with different seasons, different times of day and night and the user's production process.

3) Voltage fluctuations cause accidents or failures of certain equipment in the power network.

3. Cause harm

1) Increase the power and energy loss of the grid;

2) Cause voltage waveform distortion, increase the high order harmonics of the power network, and lead to overvoltage in serious cases, endangering the safety of the network and equipment;

3) Voltage fluctuations caused by voltage fluctuations of the external power supply network or load changes, resulting in the end equipment not working normally;

4) Affect the product quality of users.

4. Solutions

Three-phase fully automatic compensated voltage regulator is installed on the low voltage side of the transformer. The regulator is suitable for keeping the output voltage stable automatically when the voltage fluctuation of the external power supply network or the load changes. The problem of intermittent oscillation compensation for voltage regulation interference is solved effectively. The regulator reduces the frequent fluctuations of electrical components, causing unnecessary fluctuations in the power supply system. Thus effectively extend the service life of the equipment. This series of regulators is safe and reliable, suitable for a wide range of loads, and can work continuously for a long time. Cabinet installation, easy installation, easy maintenance.
