The synchrophasor program began March 30, 2010 and is scheduled to deploy 165 PMUs throughout the MISO region.
MISO President and Chief Executive Officer, John R. Bear, explains, “Synchrophasors bring a new level of situational awareness to grid operators. The ultimate goal of this three-year project is to enhance visibility of the network in real time so we can more quickly and accurately manage power flows within the Eastern Interconnection. Collaboration with our members on this smart grid technology has laid the foundation for using these advanced tools to enhance awareness of system stability.”
Synchrophasors enable MISO’s grid operators to view vital measurements of real-time system conditions in detail previously impossible to achieve. PMUs collect data 30 times each second, compared to the previous once every four seconds. Plus they are GPS time-stamped. Understanding time-synchronized measurements for voltage and current lets utilities anticipate and analyze potential disturbances. Synchrophasors also provide data essential for post-mortem analysis of stressful situations on the grid.
MISO is now collecting synchrophasor data from the 44 member PMUs installed on 10 of its members’ systems, including Indianapolis Power & Light Company (IPL), which has installed seven units at six of its substations.
Joe Bentley, IPL’s Vice President of Power Delivery, observes, “The partnership and collaboration between IPL and MISO has been outstanding during this Smart Grid Investment Grant project. The PMUs are giving us a better understanding of our transmission system while providing valuable real-time data to MISO for overall transmission grid reliability.”
Other MISO members in the project include: Ameren, Duke Indiana, Great River Energy, Hoosier Energy, International Transmission Co., Manitoba Hydro-Electric Board, MidAmerican Energy Company, Minnesota Power, Northern Indiana Public Service Co., Otter Tail Power Company, and Vectren Corporation.
The next phase of the project consists of developing applications that will analyze the data collected so operators will have a clearer picture of stress points on the grid and can make adjustments accordingly.
