The document summarizes AMSC's Distribution Static VAR Compensator (D-SVCTM) system. The D-SVC system uses solid state switching to provide fast, accurate reactive power compensation at the distribution level to maintain steady voltages for large inductive loads. It eliminates problems like voltage sags, flicker, transients and ringing that can be caused by loads like motors and welders. The D-SVC system is compact, reliable with no moving parts, and requires minimal installation and maintenance time. It provides an affordable alternative to infrastructure upgrades to improve power quality for industrial facilities and utilities.
Voltage Sag Mitigation in Utility Connected System Using Current Source Conve...IDES Editor
This paper discusses the implementation of current
source converter based distribution type static synchronous
compensator. For eliminating the lower order harmonics, the
power semiconductors are switched by pulse width modulation
technique. Current source converter, input filter, dc link
reactor are combined to design the proposed CSC based
STATCOM. Since the STATCOM is a current injection
device, the performance of the device is improved by a currentsource
converter (CSC) combination. So a controllable current
is generated at the output terminals of the device. Filter circuit
at the input terminal is designed to eliminate the higher order
harmonics. The proposed D- STATCOM is simulated and the
results are validated using MATLAB.

New Approaches for Maintenance Grounding in Medium Voltage SwitchgearSchneider Electric
Copyright AIST Reprinted with Permission. Presented at the 2013 Iron and Steel Technology Conference and Exposition (AISTech 2013). Maintenance grounding is a traditional and proven method for protecting electrical workers during medium voltage switchgear maintenance. When properly applied, it eliminates dangerous differences in electric potential, and can redirect harmful current during events such as unforeseen induced voltage from motors and generators, accidental bus contact with adjacent live parts, or human error that causes equipment to be re-energized.

Installing, Programming & Commissioning of Power System Protection Relays and...Living Online
The continuity of the electrical power supply is very important to consumers especially in the industrial sector. Protection relays are used in power systems to maximise continuity of supply and are found in both small and large power systems from generation, through transmission, distribution and utilisation of the power. A good understanding of their application, operation and maintenance is critical for operating and maintenance personnel.
In this workshop, you will gain a thorough understanding of the capabilities of power system protection relays and how they fit into the overall distribution network. The practical sessions covering the calculation of fault currents, selection of appropriate relays and relay coordination as well as hands-on practice in configuring and setting of some of the commonly used types of protection relays used in industry will give you an excellent understanding. Simulation software and real relays (but at safe voltages) will be used to give the participants practical experience in setting up and configuring the various power parameters. Both electro-mechanical and microprocessor relays will be used to demonstrate the key configuration settings required and the major differences in the approach adopted between these two classes of relays.
The strengths and weaknesses of the latest microprocessor (or numerical) relays as compared to the older electromechanical relays will be outlined. You will also gain a solid appreciation of how the modern relay communicates not only to the central SCADA system but also between themselves resulting in a truly multifunctional system which includes protection, control and monitoring. Finally, you will gain a solid understanding of issues of reliability and security for the modern relay.

Electrical Substations and Switchyard DesignLiving Online
Electrical substations form important nodal points in all power networks. Substations can be of various capacities, voltages, configurations and types depending on what is the application for which the substation is being designed. Location and layout of a substation present a number of challenges to the designer due to a large variety of options available to a designer. There are ever so many constraints too that need to be kept in mind; technical, environmental and naturally financial. Arriving at an optimum design within these constraints is as much an art as it is a science. Designing a substation which will operate with utmost reliability for at the least three or four decades involves a thorough knowledge of the current state-of-the art equipment, emerging technologies, the tools for presenting and evaluating all available options and a good appreciation of power system operation and maintenance. This course will present a comprehensive capsule of all the knowledge essential for a substation designer and walk the participants through the substation design process using a set of interlinked case studies.

Sag mitigation in distribution system by using Dynamic voltage Restorer (DVR)IJERA Editor
Power quality is most important concern in the current age. It’s now a day’s necessary with the refined devices, where performance is very perceptive to the quality of power supply. Power quality crisis is an incidence manifest as a typical voltage, current or frequency that results in a failure of end use equipments. One of the major crises dealt here is the power sag. Perceptive industrial loads and distribution networks suffer from different types of service interruptions and outages which results in a major financial loss. To improve the power quality, custom power-devices are used. The device considered in this work is Dynamic Voltage Restorer. This paper shows modelling, analysis and simulation of a DVR test systems using MATLAB.
I have considered single line to ground fault for linear load. The role of DVR is to “compensate load voltage” is examined during the different fault conditions like voltage sag, single phase to ground faults.

AMSC’s D-SVC™ (Distribution Static VAR Compensator) is a cost-effective, highly
reliable solution that allows large electric loads to operate on the AC power
system while minimizing the impacts of voltage sags and flicker problems.
AMSC’s D-SVC system automatically applies VARs on a cycle-by-cycle basis to
maintain steady line voltages adjacent to large inductive loads such as motors,
welders, arc furnaces, and pipeline pumping stations. The D-SVC uses AMSC’s
proven transmission-level D-VAR®
STATCOM control platform to bring a
transmission-level solution to the distribution environment.
Increasing grid and industrial power quality
for greater economic performance
Distribution Static VAR
Compensator (D-SVC™
) System
Overview
Reduce start-up processes, lower
maintenance cost, extend life
of equipment
A highly reliable source of electricity is crucial
for end users. Flicker, or rapidly occurring
voltage sags caused by sudden and large
increases in load current, is commonly caused
by rapidly varying loads that require a large
amount of real and reactive power such as
welders, motors, rock-crushers, sawmills,
pipeline pumping stations, and shredders. Poor
power quality caused by rapid and repeated
voltage fluctuation can dramatically reduce
production capacity, damage sensitive
equipment and can cause major downtime,
reducing overall revenues and profits.
Fix the source of the power quality
problem while providing benefit to
others nearby
Power quality has also become a major utility
issue as they seek to isolate the customers who
cause voltage sags and flicker from other utility
customers on the same circuits. Voltage sags,
transients and voltage flicker are the most
common power quality problems. Sags,
temporary reductions in voltage, will cause
loss of motor capacity and can interrupt
sensitive customer operations, interfering
with variable-speed drives, relays and robotics.
Sags and flicker are not isolated to the facility
that causes it; others miles away from the
source of the problem but on the same circuit
can be adversely affected. AMSC’s D-SVC
system mitigates the source of the problem
while providing inherent power quality
improvements to other key customers on
the connected network.
Benefits
Fast, accurate VAR compensation
connected at the distribution voltage level
The AMSC D-SVC system’s advanced design
utilizes solid state switching for fast accurate
VAR compensation connected at the
distribution voltage level. The D-SVC system’s
control logic monitors distribution system
performance (voltage and load current),
adjusting VARs on a cycle-by-cycle basis
if necessary. The result is optimal system
performance, even under wide swings in
circuit loading.
