Fiber Optics for the Power Sector:
The National Power Grid in any country is the high-voltage electric
power transmission network, connecting power stations and major
substations and ensuring that electricity generated anywhere within
the country can be used to satisfy demand elsewhere. In order to
monitor, supervise and control the power grid in an effective and
efficient manner a hierarchical load dispatching systems are employed.
In order to perform the load dispatch function efficiently, online
acquisition of power system data and its real time processing is
performed by computer based Supervisory Control and Data Acquisition
(SCADA) system. There has been a significant improvement in
Information and Communication Technology (ICT) infrastructure in power
sector in the last decade.
The telecommunication facility presently available between power
stations and substations comprises PLCC, Microwave and Optical Fiber
Communication systems. The Optical Fiber Communication system for the
transmission of speech, data and other signals is becoming
increasingly important because of its advantages viz; low attenuation,
high band width, small physical cross-section, immunity to
electromagnetic interferences, and security. ...
