POWER GRIDS SCENARIO It is an ordinary day in the control room for the power grid. Suddenly, a few alarm indications start dropping in. Obviously, there is some problem large enough that the grid equipment is starting to respond by automatic switch-offs. Five minutes later, there are several hundred alarms per second. It is impossible to understand what is happening, and one minute later, there is a state-wide blackout, costing several hundred million dollars. ANALYSIS Large blackouts are usually preceded by a short time period when the problems build up. This can last from a minute to several hours. Because of the large number of alarms, so-called alarm cascades, it is impossible to analyse the situation and find the root cause or causes. SOLUTION GoalArt's alarm analysis can analyse an alarm cascade and present the root causes in the speed of several 1000 alarms per second. This means that a GoalArt system could help the grid operators to understand the fault situation during the build-up period, and perform a graceful shut-down, instead of waiting blindly for the blackout. BENEFITS A GoalArt system will increase grid availability and turn major blackouts in to graceful shut-downs resulting in minor inconveniences and costs only. A system will be paid for after the first avoided blackout. GoalArt can read the physical topology of the grid from existing databases, and generate the MFM model automatically. There is zero modeling effort. Just plug in the system and start using it. The system can read databases in all formats, for example, CIM, Oracle, and text-based formats.
