First, the demand analysis
The power plant is a special production enterprise with a high degree of automation. The automated production equipment relies on the safe and stable operation of the power supply system. In modern power plants, the DCS control system of the generator set includes various thermal automation devices, such as automatic adjustment assembly instruments, steam turbine electro-hydraulic digital adjustment devices, boiler interlocking and safety monitoring systems FSSS, and turbine monitoring instruments (TSI). ), coordinated control system (CCS), lubricating oil pump system, hydrogen sealed oil and gas system, main thermal power, and accident lighting power system, etc., all need a reliable power supply, which requires power in the unit itself. When the power is interrupted or the power grid is faulty, the power supply should not be interrupted. This requires the power supply system not only to have an accidental power supply that can safely shut down the unit, but also to provide a high power quality for the control, monitoring device and post-accident status parameter recording device. Uninterrupted power supply AC uninterruptible power supply.
The power plant has a highly reliable DC operating power supply. Therefore, it is necessary to configure an inverter system that has high reliability and can work with it. It is designed to ensure high-quality AC power.
Second, the basic configuration plan
SP series power special UPS is an online sine wave industrial grade AC uninterruptible power supply specially designed for the power sector. It uses high frequency carrier technology and IGBT power device to accurately control various operating parameters of UPS and provide high quality for power plants. Reliable AC power.
SP series power dedicated UPS adopts the most advanced phase balance technology, and has good stability and can work normally even in the absence of phase.
SP series power dedicated UPS adopts full-bridge inverter structure and built-in isolation transformer, which has strong impact resistance and adapts to the harsh grid environment inside the power plant.
