Recent Advances and Applications of Synchronized Phasor Measurements in Power Systems
نویسنده
چکیده
Present power systems operate in more and more difficult conditions generated by various physical and economic factors. Pushing the power system closer to its physical limits worsens the reliability and security of the general operating conditions. Hence, a better control across the entire grid, through more intensive online analysis is needed. At present, a common point of view considers that Synchronized Phasor Measurement (SPM) units and Flexible AC Transmission Systems, along with distributed generation and storage devices are the main technologies that can successfully and efficiently address such problems. This paper presents the state of the art of the SPM technology and its applications to power systems, including results of research projects developed by the Romanian scientific community. A series of ongoing projects implemented in different countries are briefly presented. Key-Words: Synchronized phasor measurements, Global Positioning System, Power system monitoring, Power system control, Wide area monitoring and control, State estimation.

An Implementation of Two-stage Hybrid State Estimation with Limited Number of Pmu
State estimation is an important tool for power system supervision and control and the related applications. Based on the redundant measurements taken in the network, state estimation provides the most likely state of the power system. Conventional measurements were collected by the SCADA system and the measurement chain did not allow measurement synchronization. A disadvantage is that due to t...

Phasor Measurement Units (PMUs) are in growing attention in recent power systems because of their paramount abilities in state estimation. PMUs are placed in existing power systems where there are already installed conventional measurements, which can be helpful if they are considered in PMU optimal placement. In this paper, a method is proposed for optimal placement of PMUs incorporating conve...
