Integrated Substation AC/DC INVERTER power supply

Specifications

1. Integrate AC, DC UPS power supply
2. Serve for smart grid
3. Certer control and management
4. Easy servie
5. Low cost

 

 

Brief:

Smart integrated power supply meets the demand of smart grid and station integrated automation. It serves in power plants and substations, as AC/DC UPS for automation system, telecom system, monitoring system, HV switching, relay protection, signal, lighting and etc. It ensures grid safety and protection, is the core part of power generating and transmission equipments. This system integrating traditional DC power supply, 48V telecom power supply and AC UPS, which are central controlled. The three sub system use one group of batteries instead of separate battery pack for each system.  

 

Main features:

1. The rectifiers, monitors, data acquisition are modular design, easy installation and expension.

2. Data share and command: as the data platform, realize information share, monitoring and command.

3. Safety and stability: the sub system share one group of battery, easy control. The monitors and operation power supply are DC power supply, which improve stability.

4. Low cost: less cabinets and battery, low service cost.

5. Open system with IEC61850 protocol. 

 

Solutions:

1. Sinvle electric power UPS/INV cabinet, suitable for substations 110KV and lower

2. Dual UPS/INV cabinets in series or parallel connection, suitable for substations 220KV and higher
