Intelligent Integrated Power Supply System-PSDB

Brief Introduction

PSDB series intelligent integrated power supply system is designed for a variety of large capacity users of AC and DC integrated power supply system. The integrated AC and DC power supply system adopts a layered distribution architecture. The station AC power supply, DC operation power supply, power special UPS and power special inverter (INV), DC/DC conversion power supply (DC/DC) and other equipment are designed and configured in an integrated way. Through a unified intelligent network platform, the centralized power supply and unified monitoring and management of the substation power supply are realized. Then the on-line state detection is realized. Its operating conditions and information data can be displayed and converted into standard model data through the integrated monitoring device, which is connected to the station control layer switch of the local automation system in the standard DL/T 860(IEC61850) format, and uploaded to the remote control center. The station AC power supply is composed of AC panel monitoring module, AC monitoring module, switch quantity monitoring module,
automatic transfer switch ATS, incoming plastic-case switch, current transformer, intelligent power meter and feeder circuit breaker. It realizes the power distribution and protection from station power AC output to rectifier module, and fundamentally guarantees the safe and reliable switching of power supply. Dc operating power supply is a power supply that can reliably supply power to all control loads and various power loads in the substation under normal and accident conditions. The DC power system consists of DC panel monitoring module, rectifier module, buck module, battery inspection module, insulation monitoring module, switch quantity monitoring module, power distribution unit, and battery pack.

Suitable for power plants, hydropower stations, all kinds of substations, switching stations and other users using DC equipment, to provide a stable and reliable power supply for a variety of network communication instruments and equipment, and to ensure the safe and reliable operation of communication equipment.
