Real Time and Wireless Smart Faults Detection Device for Wind Turbineschokrio
In new energy development, wind power has boomed. It is due to the proliferation of wind parks and their operation in supplying the national electric grid with low cost and clean resources. Hence, there is an increased need to establish a proactive maintenance for wind turbine machines based on remote control and monitoring. That is necessary with a real-time wireless connection in offshore or inaccessible locations while the wired method has many flaws. The objective of this strategy is to prolong wind turbine lifetime and to increase productivity. The hardware of a remote control and monitoring system for wind turbine parks is designed. It takes advantage of GPRS or Wi-Max wireless module to collect data measurements from different wind machine sensors through IP based multi-hop communication. Computer simulations with Proteus ISIS and OPNET software tools have been conducted to evaluate the performance of the studied system. Study findings show that the designed device is suitable for application in a wind park.
Estimating Reliability of Power Factor Correction Circuits: A Comparative StudyIJERA Editor
Reliability plays an important role in power supplies, as every power supply is the very heart of every electronics equipment. For other electronic equipment, a certain failure mode, at least for a part of the total system, can often be tolerated without serious (critical) after effects. However, for the power supply no such condition can be accepted, since very high demands on the reliability must be achieved. At higher power levels, the CCM boost converter is preferred topology for implementation a front end with PFC. As a result significant efforts have been made to improve the performance of high boost converter. This paper is one the effort for improving the performance of the converter from the reliability point of view. In this paper a boost power factor correction converter is simulated with single switch and interleaving technique in CCM, DCM and CRM modes under different output power ratings and the reliability. Results of the converter are explored from reliability point of view.
The need for power generation in India increases day by day due to various factors.
Nearly 70% of the power production is from the thermal power plants in various locations of the
country. Monitoring and control of these power plants at all times is a must, since these power
plants are operated continuously. Boiler is the major part of any thermal power plant. Hence
monitoring the boiler parameters such as temperature, pressure and humidity are of great
importance in power plant. It is not always possible for continuous monitoring in the plant
premises because of an unpleasant industrial environment. In this project it is proposed to
develop remote monitoring and control of boiler parameters using wireless communication. The
proposed method provides a complete solution for these constraints in remote monitoring by
using various sensors for temperature, pressure and humidity measurement. This method uses
Internet of Things (IoT) as the platform of communication. The proposed method also provides
an option for monitoring and control even in remote location in addition to the control room.
Internet of Things (IoT) will play a major role in the future concept of power plant integration.
The proposed method will suit and provide a start-up initiation for this future concept.

Condition Monitoring of DC Motor using Artificial Intelligence Techniqueijsrd.com
The complexity of most steel industry always tends to create a problem in monitoring and supervision system. Prompt fault detection and diagnosis is a best way to handle and tackle this problem. Dc motor plays a very vital role in steel industry and there is a strong demand for their reliable and safe operation. The history of fault diagnosis and protection of electrical machines is as old as such machines themselves. However, nowadays, condition monitoring of electrical machines has become increasingly essential. It plays a very important role in their safe operation and helps to avoid heavy production losses in industry. The conditioning monitoring and fault-detection techniques of electrical machines have moved in recent years into artificial intelligence techniques. When an artificial intelligence technique is used, fault detection and evaluation can be accomplished without an expert. In this paper, artificial intelligence (AI) techniques are used to build a condition monitoring system that has incremental learning capabilities. The condition-monitoring of dc motor using AI technique schemes have concentrated on sensing specific failure modes in field windings.

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.
A vertical wind turbine monitoring system using commercial online digital das...IJECEIAES
The output of a green energy generator is required to be monitor continuously. The monitoring process is important because the performance of the energy gen- erator needs to be known and evaluate. However, monitoring the generator manu- ally and efficiently is troublesome. Moreover, when most of the energy generator located at uneasy to reach or at a very remote place. Added to the cost, human intervention for the monitoring process contributes to the unnecessary bill. All the highlighted limitations can be overcome using an internet cloud base system and application. Most of the existing data logging instruments use a memory card or personal computer in their operation. The stored data is accessible only at a dedicated computer alone. This work presented a complete energy generator interface with a commercial online digital dashboard. The digital dashboard, parameters of the wind turbine, such as the amount of power generates and the magnitude of instantaneous voltage can be monitored, and the recorded data can be accessed quickly, at any time and anyplace.
- The failure caused by fatigue has a majority
of share in the industries. The recent trends and studies
have shown that 85 to 90 % components fail not due to
static loading but due to cyclic loadings and fluctuating
conditions around. The most common and prominent being
the thermal fatigue failure. Due to uneven temperature
conditions the components under cyclic loading tend to
show a decreased fatigue life as compared to the ideal
conditions thus their probability of failure is quite high and
sometimes dangerous too. There are many techniques
which are used to identify the failure signs and take proper
action but all these techniques require a physical and nondestructive testing of the component which is time
consuming and not suitable for critical operation
components also the temperature factor is not considered
although it being the major affecting factor. This paper
presents an approach to do the online temperature analysis
of the conditions and predict the further failure conditions
by analysing the thermal stresses caused and preventing
the potential sudden failure of the component by using
polynomial regression algorithm to predict the
temperature conditions based on the initial conditions and
correlating it to the magnitude of thermal stress induced
and analyzing the failure possibility of the component

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
