Unbundling of electricity supply systems and the introduction of new technologies in all areas of generation, transmission and distribution has made power system operation more complex. Supervision of generator performance according to Grid Codes and Connection Conditions, the stability supervision of large transmission networks at specific locations, verification of power quality criteria in distribution as well as the determination and analysis of key system parameters has generated the need for power system monitoring and grid supervision beyond classical fault recording and SCADA based trending systems. Under those aspects, wide area monitoring (WAM) via phase measurement units (PMU) is just one special feature out of all monitoring applications. The PowerFactory Monitor fully integrates with DIgSILENT PowerFactory software offering easy access to recorded data, analysis of trends, verification of system upset responses and test results.
In addition to on-line grid supervising functions, the PowerFactory Monitor is an excellent high-end general purpose measurement instrument for all kind of plant tests typically performed to support device and plant modelling as well as parameter identification to allow for precise power systems simulation tasks.
The PowerFactory Monitor interacts perfectly with the DIgSILENT power system analysis software PowerFactory featuring seamless integration of system and plant tests, plant modelling and parameter identification.
The DIgSILENT PowerFactory Monitor is an integrated, multifunctional data acquisition system that covers recording, monitoring and analysis of signals in all relevant time frames. It is especially designed to cover all needs of Transmission, Distribution and Generation on all voltage levels. Flexible hardware and software components allow for the configuration of portable systems, stand-alone cabinet mounted installations as well as LAN based multiple units, multiple location systems being coordinated and supervised via Master Stations.
Any quantity deviating from normal conditions is recorded and analysed. In addition, on-line analysis of signals is provided featuring the detection of inherent problems like system and control oscillations, deviations from connection conditions or power quality aspects. The PowerFactory Monitor is a stand-alone system including all necessary hardware and software functions for signal conditioning, signal conversion, data storage and processing, calculation and documentation. In addition, remote access is possible via modem, TCPI/IP networks, WWW and special SCADA interface techniques. Several monitoring systems can be synchronized to 1œs using GPS clock for precise parallel sampling, e.g. a basic requirement for system wide area phasor measurements.
