The other day I reported on standards for synchrophasor measurements. The question was and still is: Could synchrophasor measurements prevent huge black outs? Some say yes – others say maybe or no.
Today it has been reported by Platts (Atlanta) that “The installation of phasor measurement units on part of the power grid affected by the September 8 power outage in Arizona, California and Mexico is aiding the data collection process as entities look into the cause of the outage, the head of the North American Electric Reliability Council said Monday. … Synchrophasors provide precise measurements of critical grid operating data from devices called phasor measurement units, which inform operators of conditions on a real-time basis. The goal of having the units in place is to help operators see conditions deteriorate and take actions to avoid large outages, Paul Barber of the NERC board of trustees said Tuesday.”
Obviously the synchrophasor measurements could not prevent the power outage on September 8, 2011. There needs to be experts to interpret the values!! and understand what to do to stabilize the electric system … or software needs to be written by experts …
What is missing in many organizations to keep control over the electric power delivery system? Peopleware!! Well educated Experts that understand the electrical system !! Measurements are a tool: Even a fool with a tool is a fool. And: A fool with a tool can foul-up a system much faster than a fool without a tool. In this regard, IEC 61850 is also just a tool.
