A MULTI-SIGNAL PROC SYS FOR HIGH-SPEED MONITORING-FACTS EQUIP-ELEC POWER SYS-C50

Flexible AC Transmission Systems (FACTS) are thyristor based means for highly

dynamic load flow control in electrical power supply and distribution. These new

appliances have an impact on network parameters like transmission angle, node

voltage, line current and harmonics. Thus the control of FACTS equipment

provides a highly dynamic view of these parameters. For this purpose we

developed the digital prototype of a Network Online Monitoring System (NOMS)

which is based on a multi-signal processing architecture to monitor the

influence of FACTS-equipment on the power system. It includes the recording and

analogouse processing of test input signals, A/D and D/A conversion and various

methods of digital signal processing such as complex digital filtering, space

phasor blocking and discrete Fourier transformation. Real-time signal processing

requires high calculation power that is provided by the parallel processing

architecture of TMS320C50 with a flexible global and local memory management,

high-speed bus arbitration and a smart PC/AT-interface for long-ter investigations and controls. The software algorithms are specified, for power

systems and comprise several levels of processing priorities optimizing the

available calculating time. A prototype of a NOMS has been successfully tested

in a Transient Network Analyzer (TNA) of power supply and distribution system

at our University.
