Secondary System Optimization
• Divided two planes (Control and Monitoring):• Dispatching and monitoring planeDispatching and monitoring plane
- The real-time requirements: Quasi real time system- Control direction: active control, strong plan, human computer Co t o d ect o act e co t o , st o g p a , u a co pute
interaction
• Emergency control planeEmergency control plane- The real-time requirements: Hard real time system- Control direction: passive control, closed-loop control, p , p ,

Secondary System Optimization
• The optimization and integration thought:• Basic: data steam control stream data quality• Basic: data steam, control stream, data quality
• Goal: To improve the performance , simplify the equipment
• Principle: IED integration in same plane between bays and application

Secondary System Optimization
• The optimization and integration in station level• Substation business data fusionSubstation business data fusion• Full data share• Advanced application software of power systemd a ced app cat o so t a e o po e syste
- Dispatching sequence control
- VQC in substation
- ……
• Interaction with dispatch centre- Unify the model for IEC61850 and IEC61970- Maintenance of model and graphic

• The optimization and integration in station level• Smart gatewaySmart gateway
- Data share: BCU, protection, power meter, PMU, online monitoring of primary equipmento to g o p a y equ p e t
- Data model maintenance: IEC61850 to IEC61970 CIM- Graphics maintenance: Dispatching centre use the graphics p p g g p
done in substation HMI.

Network–in substation
• More reliable and simple architecture in planning ……• HSR(High-Availability Seamless Ring):No networkHSR(High Availability Seamless Ring):No network
storm risk;• PRP(Parallel Redundancy Protocol):at link layer, No ( a a e edu da cy otoco ) at aye , o
occupation of IED’s CPU;
14
Network–in substation
• HSR+PRP:• Face to bay,no external influence to communication inter-bay
Reliable redundance• Reliable redundance• Save ethernet switch:for 220kv typical substation: 16 vs 44
switchs
15
Network–in substation
• Network traffic control technology of IED:• SV+GOOSE < 100M
16
Network–in substation
• Network traffic control technology of IED:• SV+GOOSE > 100M, maybe IED1 GOOSE port net storm happeny p pp• Important SV data is dropped

Network–in substation
• Network traffic control technology of IED:• SV+GOOSE > 100M , maybe IED1 GOOSE port net storm happeny p pp• GOOSE data is dropped by traffic control module in switch before
output

Network – Inter substation
• Network inter substation• Stability control system(special 2M point to point vs ethernet)• Stability control system(special 2M point to point vs ethernet)
• Area Protection and Control system)
P t ti d t l WAN Di t hi d t t k• Protection and control WAN vs Dispatching data network
19
Network–inter substation
• WAN framework• Extend of process level data network• Extend of process level data network
• Peer to peer communication inter substation
