What does "UPS" and "DPU" mean in power plants?
UPS (Uninterruptible, Power, System), that is, uninterruptible power supply, is a kind of energy storage device, inverter as the main component of constant voltage constant frequency uninterruptible power supply. Used primarily to provide uninterrupted power supply to a single computer, computer network system, or other power electronic equipment. When the power input is normal, UPS electric voltage supplied to the load, the UPS is an AC power regulator, it is also the built-in battery; when the power interruption (outage), UPS will immediately machine battery power through the inverter conversion method continue to supply 220V AC power to the load, the load to maintain normal working load and protection of software and hardware is not damaged. UPS devices usually provide protection against too large voltages and too low voltages.
UPS uninterruptible power outage, maintain the normal operation of the electrical equipment.Distributed processing unit DPUDCS control system in CPU, and the equivalent in computer program memory.
DPU (Distributed, Processing, Unit), that is, the decentralized processing unit, is often used in DCS control systems.Explanation: it is a station on WDPF high speed highway. Sometimes, DPU is also known as multi purpose MAC controller (Controller MultiApplication). It can execute the control strategy of engineer configuration, it can realize discrete ladder logic control, and also realize continuous regulation control. DPU can perform more than 70 special functions and more than 150 process control algorithms. In addition, it can realize data acquisition, scale transformation, alarm limit check, operation record, sequence event recording and so on.
