The document discusses issues related to power quality that can negatively impact industries. It notes that irregularities in power supply can cause problems like worn out motors, lost data, erroneous robot movement, downtime, and increased maintenance costs. It presents two types of solutions: utility-based solutions like FACTS devices controlled by utilities, and customer-based solutions like custom power devices controlled by customers. Reliable power is important for modern manufacturing equipment, and power quality issues can cause shutdowns that result in economic losses. While utilities can cause problems, many issues happen within industries due to non-linear loads causing disturbances.

The industries may undergo burned-out motors, lost data on volatile memories, erroneous motion
of robotics, unnecessary downtime, increased maintenance costs and burning core materials
especially in plastic industries, paper mills & semiconductor plants as an outcome of the above
irregularities.
The solutions put forth as a consequence of the above mentioned anomalies are called as utility
based solutions and customer based solutions respectively. The finest examples for those two
types of solutions are FACTS devices (Flexible AC Transmission Systems) and Custom power
devices that are based on solid state power electronic components. FACTS devices are controlled
by the utility, whereas the Custom power devices are operated, maintained and controlled by the
customer itself and installed at the customer premises.
The achievements of the mechanical objectives were conceivable simply because the cutting
edge enterprises had the option to discover inventive innovations that have effectively become
innovative turns of events. Constant creation all through the period is guaranteed just when the
last target is to improve the creation while achieving most extreme benefits and achieving limited
creation costs.
The explanation behind requesting top notch un-interruptible power during creation process is
principally a direct result of the cutting edge manufacturing and procedure types of gear that
work at high effectiveness requires stable and deformity free power flexibly for the fruitful
activity of their machines. Machines, delicate to power gracefully varieties are to be structured

all the more unequivocally. For example, a few instruments like flexible speed drives,
mechanization gadgets, power electronic segments and so on fall into the above classification.
Suspension to give the necessary quality power yield may here and there cause total shutdown of
the businesses which will make a critical monetary misfortune to the business concerned.
Anyway fault because of corrupted quality can't be basically put on to the hands of the utility
itself. It has been seen that in enterprises, the greater part of the conditions that can upset the
procedure are created inside the business itself. For instance, the majority of the non-direct loads
cause homeless people which can influence the unwavering quality of the power gracefully.
Following referenced are some deviant electrical conditions that can disturb a procedure caused
both at the utility and the client end.
1. Voltage Sags
2. Stage Outages
3. Voltage Interruptions
4. Homeless people because of Lighting loads, capacitor exchanging, non direct loads, and so
forth.
5. Harmonics

The businesses may experience wore out engines, lost information on unstable recollections,
mistaken movement of mechanical technology, superfluous vacation, expanded upkeep expenses
and consuming center materials particularly in plastic ventures, paper factories and
semiconductor plants as a result of the above anomalies.

Modeling Analysis& Solution of Power Quality Problems Using DVR & DSTATCOMijsrd.com

��

A Power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency that results in a failure or a disoperation of end use equipment. Utility distribution networks, sensitive industrial loads, and critical commercial operations all suffer from various types of outages and service interruptions which can cost significant financial loss per incident based on process down-time, lost production, idle work forces, and other factors. With the restructuring of Power Systems and with shifting trend towards Distributed and Dispersed Generation, the issue of Power Quality is going to take newer dimensions. The aim therefore, in this work, is to identify the prominent concerns in the area and thereby to recommend measures that can enhance the quality of the power, keeping in mind their economic viability and technical repercussions. In this paper electromagnetic transient studies are presented for the following two custom power controllers: the distribution static compensator (DSTATCOM), and the dynamic voltage restorer (DVR). Comprehensive results are presented to assess the performance of each device as a potential custom power solution.

Novel Cost-effective Technique for Continued Operation of Electrical Equipmen...CSCJournals

��

This research focuses on mitigating voltage sags at the control level through a cost-effective method using mini dynamic sag corrector at low voltage systems and proposing control level embedded solutions for equipment design and modifying the technical aspects of electrical devices to facilitate the control circuit to ride-through voltage sags. Voltage sags also known as “dips” are a common cause of power disturbances. These are temporary voltage drops below 90% of the nominal voltage caused by a sudden increase in loads or short circuits and faults lasting up to 170ms. Voltage sag in distribution networks can adversely affect sensitive electrical equipment in industrial processes, such as production and manufacturing, resulting in substantial financial losses of up to $1.5 million/day. Various types of electrical equipment are susceptible to voltage sags but are not limited to power supplies, relays, contactors, variable frequency drives, and programmable logic controllers. In this method, the cost-effective MiniDySCs were installed in the industrial plant to compensate for the missing voltage in the lines during a sag event. Also, modifications to technical aspects of Contactors, Relays, and VFDs are proposed to provide more robust results for the control circuits to ride through voltage sags even up to 40% of the nominal voltage-drop.

AUTOMATIC VOLTAGE CONTROL OF TRANSFORMER USING MICROCONTROLLER AND SCADA Ajesh Jacob

AUTOMATIC VOLTAGE CONTROL OF TRANSFORMER USING MICROCONTROLLER AND SCADA LABVIEW PROJECT FINAL YEAR EEE ABSTRACT: A tap changer control operates to connect appropriate tap position of winding in power transformers to maintain correct voltage level in the power transmission and distribution system. Automatic tap changing can be implemented by using µC. This improved tap-changing decision and operational flexibility of this new technique make it attractive for deployment in practical power system network. This paper deals with the implementation of µC based tap changer control practically, using special purpose digital hardware as a built-in semiconductor chip or software simulation in conventional computers. Two strategies are suggested for its implementation as a software module in the paper. One is to integrate it with the supervisory system in a substation control room operating in a LAN environment. In this configuration, the parallel transformers can be controlled locally. The other is to integrate it into the SCADA (Supervisory Control and Data Acquisition) system, which allows the transformers to be monitored and controlled remotely over a wide area of power-network. The implementation of µC based tap changer control needs interfacing between the power system and the control circuitry. µC s may need to interact with people for the purpose of configuration, alarm reporting or everyday control. A human-machine interface (HMI) is employed for this purpose. An HMI is usually linked to the SCADA system’s databases and software programs, to provide trending, diagnostic data, and management information such as scheduled maintenance procedures, logistic information, detailed schematics for a particular sensor or machine, and expert-system troubleshooting guides. OBJECTIVES: The original system can afford the following features: - Complete information about the plant (circuit breakers status, source of feeding, and level of the consumed power). - Information about the operating values of the voltage, operating values of the transformers, operating values of the medium voltage, load feeders, operating values of the generators. These values will assist in getting any action to return the plant to its normal operation by minimum costs. - Information about the quality of the system (harmonics, current, voltages, power factors, flickers, etc.). These values will be very essential in case of future correction. - Recorded information such case voltage spikes, reducing the voltage on the medium or current interruption. - implementation of µC based tap changer control practically, using special purpose digital hardware as a built-in semiconductor chip or software simulation in conventional computers.

��

Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution. Pollutants of major public health concern include particulate matter, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide. Outdoor and indoor air pollution cause respiratory and other diseases and are important sources of morbidity and mortality. WHO data show that almost all of the global population (99%) breathe air that exceeds WHO guideline limits and contains high levels of pollutants, with low- and middle-income countries suffering from the highest exposures. Air quality is closely linked to the earth’s climate and ecosystems globally. Many of the drivers of air pollution (i.e. combustion of fossil fuels) are also sources of greenhouse gas emissions. Policies to reduce air pollution, therefore, offer a win-win strategy for both climate and health, lowering the burden of disease attributable to air pollution, as well as contributing to the near- and long-term mitigation of climate change.
