Wide area synchronized frequency measurement system architecture with secure communication for 500kV/220kV Egyptian grid

摘要

Continuous and reliable supply of electricity is required for Egypt's socio-economic development. With a highly urbanized population and a high growth electricity demand, a systematic expansion of the electricity generation facilities and other infrastructure developments are imperative to cope with household demand. At the same time, economic growth will hinge on the provision of adequate and reliable power to vital sectors like industry, agriculture, tourism and transport sectors. Against this background, the Egyptian power system has had to confront some major operating problems in voltage regulation, power flow control, protection, and stability. Wide-area monitoring systems (WAMSs) utilizing synchrophasor measurements can help with understanding, forecasting, or even controlling the status of power grid stability in real-time. This paper introduces infrastructure to cape with the world in solving the wide area power system from the protection to coordination and then control action. The architecture of the wide-area synchronized measurement used for on-line monitoring and application is discussed. The paper introduces real time structure of a number of Frequency Disturbance Recorders (FDRs) devices deployed across various locations in the Egyptian power grid and connected to a server through a secure communication infrastructure for collecting data, displaying many of parameters such as voltage, current, phases, etc. and provide some data analysis for future control and analysis. It has served utilities, academics, and policy makers with reliable and valuable synchrophasor data from 500kV/220kV Egyptian grid.
