WASAS Design Considerations/Requirements

4


• Not a synchrophasor data only system – a wide-area situational awareness system primarily for use by control center operators

– EMS/SCADA data– Non-electrical data (weather, fire, traffic, earthquake, etc.)– More will be added in the future!!!

• Not a standalone system – must interface with variety of external systems

– Other SCE systems, such as EMS/SCADA, engineering database, etc.– External data servers for weather, fire, traffic, earthquake data– Synchrophasor data from phasor systems of other utilities (e.g. WECC

member utilities)– May interface with more SCE internal and external systems in the future

WASAS Design Considerations/Requirements

5


• Will need to evolve to become a wide-area monitoring, protection and control system (WAMPACS) over the time

– Must be able to support all types of wide-area monitoring, protection and control applications

• System expansion anticipated– More phasor measurements from SCE and others– Other data (e.g. IED data)

• Will be part of SCE’s overall Smart Grid deployment– Leverage SCE existing IT infrastructure and common services

WASAS Design Considerations/Requirements (cont.)

6


• Current WASAS deployment complete by end of 2011 as an approved GRC project including all procurement, engineering, deployment, installation, and testing processes

• Work with NASPI to make interfaces to become open standards

• Four environments: Operation (OP), Production Test (PT), Development (DEV), and Training (TR)– Full redundancy for OP and PT– PT is exactly the same as OP

• External access of WASAS data is through WASAS external historian databases– Data are pushed from OP environment to external historian – no direct access from external
