Wide area measurement & control system in Mexico

The wide-area synchronized phasor measurement system envisioned by Comision Federal de Electricidad (CFE) during the 1990´s and designed to increase the security and integrity of Mexico´s electric power system. This paper presents the different development stages taken for the deployment of WAMS. Details of the current state and PMU data-based application examples within CFE are also provided. CFE has a potential of more than 140 Units of Mensuration Fasorial (PMU´s) and relays protection with phasor measurement functions of different manufactures and models, installed in the three different electric power systems. The project of a Wide Area Measurement System of CFE is conformed by regional data concentrators of PMU´s, located in each Regional Management of Transmission or Control Areas, and a Central Unit or super concentrator. In this Centrl Unit is possible to save the files for analysis post mortem. Also is possible the visualization in real time of voltage, frequency, fase angle, MW and MVAR in different points of the electric systems. During ten years of experience with sincrofasors, the CFE has developed applications for the analysis of fauls and reproduction of events. Also, with the registrations of PMU´s regulators, stabilizers and underfrequency load shedding schems have been adjusted. At the moment, in CFE are working in the development of applications for the Automatic Generation Shedding Schemes (AGSSs) using Phasor Measurement and Control Units PMCU´s.
