especially in developed countries, continuously encounter the challenge of
providing reliable power to the end-users at competitive prices. Due to several
reasons such as equipment failures, lightning strikes, accidents and natural
catastrophes, power disturbances and outages in substations occur and often
result in long service interruptions. Thus, the substations should be properly
controlled and monitored in order to take the necessary precautions accurately
and timely. In this respect, substation automation, which is the creation
of a highly reliable, self healing power system that rapidly responds to
real time events with appropriate actions, ensures to maintain uninterrupted
power services to the end users.
Recent developments in communication technologies have enabled cost effective
remote control systems which have the capability of monitoring the real time
operating conditions and performances of substations. Each communication
technology has its own advantages and disadvantages that must be evaluated
to determine the best communication technology for substation automation.
In order to avoid possible disruptions in substations due to unexpected failures,
a highly reliable, scalable, secure, robust and cost effective communication
network between substations and a remote control center is vital. This high
performance communication network should also guarantee very strict Quality
of Service (QoS) requirements to prevent the possible power disturbances and
outages. In this research
project, we propose a hybrid network architecture, including Internet, wireless sensor networks, wireless mesh networks, and WiMAX, to enable minimum cost and very highly reliable communication for substation automation applications.
