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.
Though the system capacity of the existing fiber network in most of
the countries is sufficient to meet to the requirements of power
system control at the present time, the network is going to become
highly complex in near future due to addition of new generating
stations and sub-stations. Further, the fiber network facility is to
be extended to other users beyond those required for the operation of
the power system network, such as companies, banks, government
departments and railways. For such users, the inception of the World
Wide Web (internet) transformed the trend from a predominantly voice
traffic to carrying data as well as video traffic. The growth in
internet traffic would cause the capacity of the fiber network to
rapidly saturate and then the network would experience fiber
exhaustion. Thus the fiber network capacity is required to be
enhanced. Since Replacement of optical cable would be highly
expensive. Also, since the fiber network systems operate in the second
transmission window, the increase in transmission capacity would
result lowest attenuation coefficient, thus expanding the repeater
distance in the network. .Therefore in order for the network to
operate at higher bit-rate, a dispersion management scheme is needed.
Researchers in this area may please suggest to find an economically
viable solution.
