Smart Grid Applications in China

3. March 2011
Smart Grid
State Grid of China firstly published the plan of developing smart grid on May 21st 2009.
Different with other countries, include
generation, transmission, substation,
distribution and scheduling
Over 55 billions USD for investment

4. March 2011 Power Station Control Center Hospital Solar Power Line Wind
Sense system overloads, monitor grid equipments, autonomously work according to conditions…
Get energy from virtually any fuel source…

Tailor energy consumption, energy saving…

5. Grid Equipment Monitoring
March 2011
Grid Equipment Monitoring
Monitoring grid equipments
monitor environmental information, like weather, vibration, inclination
Find fault circuit quickly
Prevent equipment from stolen or damage ……

6. Grid Equipment Monitoring
March 2011
Grid Equipment Monitoring
Application requirements
Device monitor environmental information, small size, low price, low energy (4~6 years)
Energy requirement of Backbone will not be so critical
Both device and backbone will be equipped in metal box
Data size is small < 50 bytes
Transmission distance:
device<->backbone, >200m; backbone<-> backbone, >2000m
470MHz , <50mW … any other available frequency and power
Topology between backbones: belt type
System delay < 30s

7. PAR of 4k Data rate < 40kbps Propagation path loss >120dB
March 2011
PAR of 4k
Data rate < 40kbps
Propagation path loss >120dB
>1000 endpoints per main powered infrastructure
Asymmetric application data flow
Endpoint must be able to conserve energy
Reliable operation in dramatically changing environments ……
Work in 4k maybe find the resolution for smart grid applications
