Optimal Substation Coverage for Phasor Measurement Unit Installations

چکیده
The PMU has been found to carry great deal of value for applications in the wide area monitoringof power systems. Historically, deployment of these devices has been limited by the prohibitivecost of the device itself. Therefore, the objective of the conventional optimal PMU placementproblem is to find the minimum number devices, which if carefully placed throughout thenetwork, either maximize observability or completely observe subject to different constraints.Now due to improved technology and digital relays serving a dual use as relay & PMU, the costof the PMU device itself is not the largest portion of the deployment cost, but rather thesubstation installation. In a recently completed large-scale deployment of PMUs on the EHVnetwork, Virginia Electric & Power Company (VEPCO) has found this to be so. The assumptionthen becomes that if construction work is done in a substation, enough PMU devices will beplaced such that everything at that substation is measured. This thesis presents a techniqueproposed to minimize the number of substation installations thus indirectly minimizing thesynchrophasor deployment costs. Also presented is a brief history of the PMU and its applications along with the conventional Optimal PMU placement problem and the scope for expanding thiswork.

Binary particle swarm optimisation-based optimal substation coverage algorithm for phasor measurement unit installations in practical systems
Phasor measurement units (PMUs) play an important role in the wide-area monitoring and protection of modern power systems. Historically, their deployment was limited by the prohibitive cost of the device itself. Therefore, the objective of the conventional optimal PMU placement problem was to find minimum number of devices, which when carefully placed throughout the network, maximised observabi...

Presenting a New Method Based on Branch Placement for Optimal Placement of Phasor Measurement Units
In this paper, a new method based on branch placement for the optimal positioning of Phasor Measurement Units (PMUs) in power systems is proposed. In this method, the PMUs are in type of single-channel and are installed at the beginning of the branches. Therefore, they are able to measure the bus voltages. Also, the installation of the PMUs on the branches increases the security of observabilit...

متن کاملOptimal Placement of Phasor Measurement Units to Maintain CompleteObservability Considering Maximum Reliability by Non-dominated Sorting Genetic Algorithm-II (NSGA-II)
Ever-increasing energy demand has led to geographic expansion of transmission lines and their complexity. In addition, higher reliability is expected in the transmission systemsdue to their vital role in power systems. It is very difficult to realize this goal by conventional monitoring and control methods. Thus, phasor measurement units (PMUs) are used to measure system parameters. Although in...
