AGENDA

• A Power Hungry China

• How to Face the Challenge

• Power Generation Solution

• T&D Solution

• Q&A


A Power Hungry ChinaHow to sustain China’s GDP Growth Rate:

– Suppose China wants to sustain its GDP at 10% rate for the next decade

– China needs to add additional 50000 MW of new generation capacity per year

– It’s equivalent to 2/3 of current total generation capacity of Great Britain

– This is equivalent to one new 100 MW power plant every week– Total investment of $590 Billion US

Limit of Relational DB for EMS

• Problem with Real-time Data in Relational DB– SCADA Data, for large T&D Network

• 2 s per each tag → 43200 value/day* 26 bytes → 1.2MB/tag·day

• 100,000 Tag EMS/Day → 112.32 GB/Day

• 100,000 Tag EMS/Year → 40,996.8 GB /Year

• AMR data, 21,000,000 meters, 1 second, 10 variables per meter

– Average Value• 15 m per each tag → 96value/day* 26 bytes →2,496 bytes /tag·day

• 100,000 Tag EMS/Day → 249.6 MB /Day

• 100,000 Tag EMS/Year → 91.1 GB /Year

– Schedule Value• 96Value ×100,000Tag = 9,600,000 Event/Day

• = 3.5 Billion Event/Year


Mission Impossible for WAMS• Problem with Real-time Data in Relational DB

– PMU for One Substation• Value: 48 Vector, 8 Analog and 20 Status → 268B(data Length)

• Bandwidth: 20 ms per frame of data = 50*268= 13KB per second

• Event: 76*50 = 3800 event/per second

– WAMS with 50 PMU• Bandwidth: 13KB * 50 = 650KB/per second

• Event: 3800*50 = 190000 event/per second

– Total Data Size• Data Stream: 650KB*60*3600= 14G/Day
