Phasor data concentrators placement in the Colombian transmission system

An assessment of the cost of implementing a Phasor Measurement System (PMS) to be used among other applications for evaluating the state estimation in the Colombian Transmission System (STN) is performed, using the costs associated with PMUs, Phasor Data Concentrators (PDCs) and leasing of existing communications networks. First, the optimized PMS topology is obtained by the optimized placement of PDCs in the STN considering different scenarios, minimizing the approximate cost of communication which is mostly dependent on the length of the communication channels and also dependent on the number of PDCs considered. Based on the results obtained for the PDCs placement, the approximate total cost of a PMS implementation is evaluated including PMUs and PDCs to compare its various components and draw some conclusions about the best implementation approach.
