| Popis: |
Complex power systems need more observability in critical situations. Synchron phasor measurement is a new technology that improves power supply reliability and quality. PMU measure various system parameters extremely precisely and rapidly. Every PMU measurement receives a GPS synchronized time stamp, thus making it possible to perform precise comparative analyses and obtain an overview of the complete system. Since system operators have to work economically and these units and their installation incur costs, they need an algorithm for their optimal placement. This paper presents a concept based on a decoupled Newton-Raphson power flow analysis and a sensitivity analysis, which helps place PMU optimally. The theory behind the algorithm is elucidated and results of a system test are presented. |
