Product Specifications
Product Description
GQH-Ad Digital is TIEON third generation solution of AC power system for substation. Through Digital AC monitoring module, the system offers network-based communication of each input module, feeder module and inverter module, establishing the digital power software platform and realizing information-sharing of AC power system. The system builds digital power hardware platform through all switches being intelligent and modular design, resulting into elimination of secondary cabling as well as cross-panel secondary cabling outside the module. The digital AC monitoring module communicates with the host computer through the Ethernet interface and IEC61850 protocol so as to make the substation power an open system.
System structure
1. Primary section:
(1) Integrates the AC input module, AC feeder module, inverter module by AC monitoring module and networking.
(2) Uses ATS (automatic transfer switching equipment) to transfer the inputs power automatically.
(3) Use AC/DC inverter module connect to the DC bus rather than UPS batteries.
2. Communication structure
(1) Each module has an RS485 communication port, which makes data be transferred and exchanged by IEC61850 digital gateway.
(2) The monitoring module collects data and communicates with remote substation automation system through IEC61850 communication protocol.
(3) Real-time monitoring on whole system through Ethernet, achieving remote and local operation of the power system.
Typical designs
1. One bus system
It is commonly used in 110kV and below transformer substation.
2. One bus divided system
This type of design is commonly used in 110kV, 220kV, 500kV transformer substation.
