Abstract: When disturbances occur in power grid, monitoring, control and protection systems are required to stop the grid degradation, restore it to a normal state, and hence minimize their effects. However, in wide area power grid resulting from large extension and interconnection with neighbor grids, classical systems based on local independent measurements and decisions are not able to consider the overall power grid disturbances and then they are not able to avoid the blackout. The introduction of the advanced measurement and communication technologies in these systems may provide better ways to detect rapidly these disturbances and protect the overall grid from the propagation of the fast-cascading outages. Indeed, the observability of the wide area power system dynamics becomes feasible through the use of these recent developed technologies. Using wide area real-time synchro-phasor measurement system based on Phasor Measurement Units (PMUs), different types of wide area protection, emergency control and optimization systems can be designed and implemented. In this talk we discuss new technologies that allow wide area grid to be well monitored, controlled and protected against any disturbances. At the beginning, we present the different steps which may be followed in order to develop PMU based Wide area measurement system taking into count quality of the power grid dynamics observability. After that, we discuss how to improve monitoring, control and protection integrated system for wide area power grid. We have already designed and implemented PMU based wide area synchro-phasor measurement system through the use of the new technologies as well as we have tested its performances for showing its experimental evaluation. Besides, we have developed some applications where these advanced technologies have been used. We will end up this talk by presenting our research work results related to this subject.
