The document discusses the evolution of microwave networks in electric utilities over four waves from the 1940s to present day. The first wave involved experimental voice grade circuits in the 1940s-1960s. The second wave from the 1970s-1980s expanded to low-medium capacity analog systems still using voice grade channels. The third wave in the 1990s-2008 involved digital microwave and migration to IP networks using T1 and SONET. The current fourth wave since the mid-2000s involves converting from T1/SONET to fully IP-based systems using Layer 3 transport protocols like OSPF and MPLS. Typical electric cooperative networks can be small, with nodes requiring low bandwidth mainly for SCADA, security, and
Wireless technology is pervading the industrial automation world, Zigbee is the first step, and it will expand rapidly thanks to miniaturization, and battery technology progress, and emerging LPWAN networks.
Design and Implementation of Low Cost Smart Web Sensors for Electric Power Qu...IJTET Journal
Abstract— The paper presents a low cost virtual instrument for monitoring the power quality events. The problem of power quality concerns the interferences which can be present in the mains. These electromagnetic disturbances can overcome a large interval of frequencies and can be present in industrial, domestic as well as commercial system .As main negative effects we can mention the high order harmonics, voltage fluctuations, flickers and disturbances with high slew-rates It is frequently indispensable to measure power quality indexes in wide electric power plant or in industrial zones. To this aim a low cost smart web sensors has been designed and implemented to acquire, process and transmit data over 802.3 network .It is organized in multi micro controller system. The first one dedicated to the data acquisition and the other to data processing, dynamic HTML pages construction and TCP/IP stack management. Key features of realized devices are low cost, data processing and remote communication capabilities, the possibility to provide data with any internet browser.

WIRELESS POWER THEFT MONITORING SYSTEMvivatechijri
Power larceny is the sizably voluminous quandary now days which causes immensely colossal loss to electricity boards. And to surmount these losses prices are incremented. So if we can obviate this larceny we can preserve lots of potency. The mundane practice for power larceny is to short input output terminals or to place magnet on the wheel in case of old meters. In this system a micro controller is interfaced with an energy metering circuit current sensing circuit, RF communication & a contactor to make or break power line. If current is drawing & energy pulses are mundane then no puissance is larceny. If current is drawing & energy pulses are not coming then it designates power larceny. So microcontroller trip the o/p utilizing relay. This information is sent to substation utilizing wireless communication. Line faults may be caused due to over current or earth fault. If there transpires to be a connection between two phase lines then over current fault occurs. Earth fault occurs due to the earthing of phase line through cross arm or any other way.
The migration to IP has placed new demands on SCADA radio system capacity with equipment designers working to satisfy spectrum efficiency demands within economic constraints. Exciting new technologies have dramatically reduced the price of efficient quadrature amplitude modulation techniques to the point where implementation in moderately priced UHF SCADA radio systems is possible. This presentation will describe some of the technology behind a new low-cost digital radio that delivers 60 bps in 12.5 kHz for use in licensed UHF frequency bands with some discussion on application examples.

A lunchtime presentation on how news has changed, how nonprofits have adapted, and what the future may hold for Association for Women in Communications at Madison, Wisc's Edgewater Hotel.
Drawing on recent research and work with both journalists and nonprofits, this session looked at how nonprofit communications strategy looks when it is updated for the Web 2.0 world. Not only do the old rules of goal, audience, message work like the did before--they actually work better online than they did back in the good old days (ie a couple years ago).
slides from several presenters on using social media in a hands-on way for nonprofits and grassroots folks.
A production of the Office of LGBT Health and the Office of Substance Abuse and Tobacco Control Programs at the Chicago Department of Public Health in collaboration with the National LGBT Tobacco Control Network.
There are lots of avenues for communication with most teams already. What we need to improve is the quality of the communication we have.
This presentation looks at two methods + models for considering communication and delivering high quality feedback.

2. Microwave Networks – Practical Considerations for
Electric Utilities
• First Wave Implementation – 1940s to 1960’s – Experimental Voice Grade
Circuits on low capacity 950 and 2 GHz analog baseband
• Second Wave – 1970’s to late 1980’s – low to medium capacity analog
baseband systems – still voice grade channels and specialized baseband
relaying channel for breaker protection on high voltage systems. Voice
applications secondary and not critical
• Third Wave – 1990s to 2008 – Digital Microwave, Conversion from
analog. Migration from 2 GHz to 6 GHz for cellular space. T1 and Sonet
OC1 and OC3 heavily implemented.
• Fourth Wave – Mid 2000’s to present day – Conversion from T1 and
SONET to IP based systems. From Layer 2 to Layer 3 transport, OSPF and
MPLS are primary conversions taking place now.
4. What Drives Private IP networks at Electric Coops
• No or unreliable
communications
• Security and Control of Circuit
• Critical Function Circuit or
Application
Fiber in Local
Telco Loop?
Private Fiber?
Private
Microwave?
12. TYPICAL SUBSTATION
SCADA , Relaying and Metering
System Control and Data Acquisition
Perimeter Security systems
Data needs are low less than 0.2 Mbps
are typical high side (excluding Video)
• Nodes in a typical electrical Substation
14. DESIGN
CONSIDERATIONS –
ELECTRICAL UTILITIES
Small Municipalities and Small
Electric Coops
- May have smaller needs and
budgets
- Or may be required to have high
reliability telecommunications
networks….
- Distribution Coops
- Transmission Coops
- Generation Coops
- Power Agencies
- Investor Owned Utilities
15. PLANNING ISSUES
Does the organization/coop have
staff to do the SCADA and Telecom
Network work?
Some want a contractor to furnish
everything
Some want project assistance and
then hand off to their internal staff
Many smaller organizations simply
do not know how to do planning,
design, implementation, and
maintenance.
Who is the decision maker or
influences the decision makers?
16. APPROACHES TO
CONSIDER
Potential clients are not the same from coop to
coop.
- Some will only buy equipment, some will buy
an entire network with maintenance
Needs assessment
- You may need to define scope and develop
planning for the coop, then do the rest…
- - or some may have partially developed
designs and want you to take over
How to approach the network
- Learn about the coop, each one is different in
organization and sometimes in functions
- Discover how to become a valuable and
reliable partner. It is almost never about
lowest cost, but highest value.
