The general evolution in the computer and automation area is affecting the way that industrial power systems are designed and operated. As part of normal plant engineering, modern power systems are always modeled in a computer simulation tool in order to enable calculation of power flow, short circuit currents, levels of harmonics and more. Modern power systems are also equipped with computer based relays and measuring devices that communicate on fast networks, making a large number of measurements and transient curves available. It has also become common practice to store measured data in historical databases for later access.
Experience shows that even though historical databases; modern relays, instrumentation and networks; and updated computer models are designed into an industrial project, it is a complex task to actually utilize all the data when the plant is in the operating phase.
The amount of data is simply too large and the speed with which the data is collected is too high for any human to manage. Unitech Power Systems provides the tools that turn this huge collection of data into information that can be used by the operator of the plant, turning IO - Integrated Operations, CM - Corrective Maintenance and FP - Fault Prediction into more than just hyped phrases.
