Disadvantages of traditional UPS power supply, improved method for UPS power supply system. Since the reform and opening up, the construction of my country's power system has no need to meet the rapid development of various industries. Improve the UPS power supply system to ensure the company's stable power supply, and the production of efficient, stable and safely.

Disadvantages of traditional UPS power 1. The traditional UPS power supply of the same voltage and the same capacity is 3-4 times of lead acid. 2, the traditional UPS power supply needs to protect the line to prevent the battery from being filled with discharge.

3 Low power and short life. 4, the tandem-type regulated UPS power supply is very obvious, its own volume and bulky transformer, and high requirements for heat dissipation, it directly hinders its miniaturization process, which is the same, which is too efficient. Very low, generally only 45%, low efficiency is low, and another deadly weak point of series-type regulation is a single voltage output, which also makes it greatly reduced by its application.

UPS power supply system Improvement method 1 Improve UPS power supply system reliability: series backup power supply mode, output master from backup mode, redundant parallel power transmission. 2 To ensure that the power supply system composed of the power regulator and the "1 + 1" UPS system, it can also work safely and reliably under the conditions of the generator power, and the original output power is 110kVA backup power generation. Units to 150kVA standby generators.

3 Duplex Redundancy Power Supply: Use "redundant" mode of operation, that is, two UPSs are used to communicate with each other by panel or parallel lines, for various faults that may happen, dual according to program settings inside the machine. Machine or click Switch, each UPS has a rated capacity to meet the requirements of all loads. 4 Duplex Non-"Redundant" UPS Power Supply: Operation relative "redundant" UPS simple, does not affect another UPS operation, meter power module redundancy, operation risk is small.

Due to two UPS distributions, reduce the impact of external factors such as the same environment, and the cable is connected to the instrument DCS cabinet for it to power, if a UPS internal fault or output cable failure causes the downtime, the DCS power module is adopted Redundant design, there is still an output without failure, does not affect normal production. The UPS system is important for discrete control system to power two uses: First, emergency use: Prevent sudden power failure and affect normal work, causing damage to the DCS system; second, instantaneous high voltage, low instantaneous "Pollution" such as voltage, wire noise and frequency offset, improve power quality to supply high quality power supplies for DCS systems. The UPS power supply system is critical to ensure the safe and smooth operation of modern communication systems.

Practice has proved that the use of the UPS alarm signal access center is controlled by the DCS system to effectively reduce the power interruption event caused by the power supply of UPS power supply, improve the security and reliability of the UPS power supply system, and the promotion of the UPS power supply has Significance. UPS after optimization is not only easy to operate, but also reduces the risk of operation and maintenance.
