Applying
Harmonic Solutions to Industrial and Commercial Power
Systems
- Problems associated with harmonic distortion
are well understood for many power system applications. However,
finding the right solution is challenging. There are at least ten
different technologies to choose from, each with specific
technical and economic advantages. This presentation will provide
recommendations for reducing harmonic distortion, improving system
capacity and improving system reliability while evaluating
economic considerations. Special considerations for applying
capacitors on a power systems with harmonics will be discussed.
Finally, opportunities for improving energy efficiency using
harmonic technologies will be explained. Author: Daniel
Carnovale, P.E.
Connection
of a Distributed Resource to 2-Transformer Spot
Network
- This article highlights an
approach taken for successful installation of a 75kW DR to a
spot network supplying an office building. In the subject case
an indiscriminate connection of DR would have resulted in
serious consequences to system integrity. The solution consisted
of applying power relays for automatic supervision of the
DR depending on the conditions in the system. The signals
were derived directly from the network protectors ensuring
full integrity of the system. Tests demonstrated that the
installation performed as designed. DR has been in operation since early
2002. Author: Martin Baier, W.E. Ferro, D.R.

Battery Life Using Soft-Load Transfer Switch
-
A power system event that exceeded the ITIC
(CBEMA) limits, cause the battery back up system to supply power
to the load. Unless the transfer switch is a "soft-load"
type, periodic generator testing will also cause a power quality
event that will cause the batteries to be exercised, reducing
their life.

Existing Supervisory Control and Data
Acquition systems require significant effort to add new field
devices, especially if these field devices don't speak the same
protocol. Learn how to overcome this problem by
installing a smart device that analyzes and consolidates
signals, then sends contact closure signals to
the existing RTU, permitting the existing SCADA system to
receive data from sophisticated new battery
monitors.

Enclosure
Cooling Calculator
-
The amount of cooling is dependant on the
dimensions of the enclosure, the paint color, the amount of
insulation and latitude of the installation. Use this
calculator to determine the amount of cooling needed. This
calculator can also be used to determine the amount of auxiliary
heating necessary to maintain a non-condensing internal
environment by raising the internal temperature above the external
ambient.
Commerical
Building Energy Usage Calculator
-
The US DOE commissioned an energy consumption
study of over 4.6 million buildings and segmented the data by type
of enterprise and by size of structure. The study did not
include manufacturing locations. To use, simply identify
your type of enterprise (education, healthcare, etc.) and the
facility size. If you know your monthly energy bill, the
calculator will compare your energy bill to the US average for a
similar building.
Predictive Diagnostics
Calculator
-
Advanced “Partial Discharge” technology now allows you to predict
imminent insulation failure within medium voltage equipment, saving the expense of
equipment loss and downtime due to catastrophic, unexpected failure. Use this
calculator to determine if this technology makes sense for your application.
Also includes a generic ROI calculator usable with any hardware or financial decision.
If you know the initial cost, annual savings and projected life of equipment, this
calculator will determine the compounded rate of return, also know as IRR.
Spot Network "Quick Check" Calculator
-
Applying a spot network instead of a secondary selective (main-tie-main)
distribution system decreases the likelihood of a power outage by 80%, but costs the same
as the main-tie-main system. The catch is that not all applications are candidates
for spot network systems. While a detailed engineering study is needed to know for sure,
use this calculator to eliminate some applications.
Distributed Generation Evaluator
-
Operating a local generator can make sense as long as local environmental
permits are updated and you have a firm understanding of the economics of operating the
generator. To help know if running a local generator makes sense, use this calculator. It uses
commonly available data from your energy bill to estimate the right size of a standby generator
and provide IRR (rate of return) costing data.
