The term load monitoring depicts the monitoring and auditing the load consumption patterns in low voltage customer side. Since energy becoming the more concerned topic of the era the work for proper auditing is a required improvement to be made in today's power system. The existing digital meters are up to accurate level of measuring data. Smart meters when compared to electro mechanical meters have to reduce man power and it should ensure capability of communicating with utility sector. Hence by using INTERNET OF THINGS, the technology of modern era and which is going to be well strengthened by forth coming 5G, there will be a successful load monitoring process. In this project the process of monitoring concentrates over the harmonics, excess loading of transformer especially in distribution side, power factor monitoring, voltage disturbances etc., Indeed the major part of the project is detection of tampering by establishing a summation algorithm between the power distributed from the transformer in distribution ends and the consumers. The power consumption and distributed data are retrieved from respective meters through and then fed to the monitoring page of electricity board. Tampering being one of the major hindrance to the electricity generation and distribution, this method of monitoring could detect any theft and immediate site inspection can resolve the issue. On the whole, monitoring the power consumption via internet of things ensures effective monitoring and detection of tampering in low voltage side of the power grid.

An accurate electric current transducer is a key component of any power system instrumentation. To measure currents power stations and substations conventionally employ inductive type current transformers .For high voltage applications, porcelain insulators and oil-impregnated materials have to be used to produce insulation between the primary bus and the secondary windings. The insulation structure has to be designed carefully to avoid electric field stresses, which could eventually cause insulation breakdown. The electric current path of the primary bus has to be designed properly to minimize the mechanical forces on the primary conductors for through faults. The reliability of conventional high-voltage current transformers have been questioned because of their violent destructive failures which caused fires and impact damage to adjacent apparatus in the switchyards, electric damage to relays, and power service disruptions. In addition to the concerns, with the computer control techniques and digital protection devices being introduced into power systems, the conventional current transformers have caused further difficulties, as they introduce electromagnetic interference through the ground loop into the digital systems. Magneto-optical current transformer(MOCT)technology provides a solution for many of the above mentioned problems. The MOCT measures the electric current by means of Faraday Effect that is the orientation of polarized light rotates under the influence of the magnetic fields and the rotation angle is proportional to the strength of the magnetic field component in the direction of optical path. MOCT is a passive optical current transducer which uses light to accurately measure current on high voltage systems and determines the rotation angle & converts it into a signal of few volts proportional to the current.

The Internet is an open space where a great number of computer systems are connected. Since many services are provided through the Internet, malicious users can easily intrude on any of those systems by using the vulnerabilities of the Internet. Although Intrusion Detection and Prevention System (IDPS) can be used to defend against such malicious activities, it is not always possible to completely protect a targeted system against the attacks. For this reason, Intrusion Tolerance Systems (ITS) has been proposed to maintain services even in threatening environments, where some malicious attacks have intruded into a system successfully. In this paper, we propose a new ITS based upon maintaining a service redundancy level to ensure that all services are properly provided to users even if a malicious intrusions such as VM (virtual machine) escape attack exists. The simulation results show that the proposed scheme can guarantee the operation of every ongoing service by maintaining the service redundancy level of all services.

Dual-tone-multiple-frequency (DTMF) controlled vehicle is a specific idea in automotive whose actions can be controlled by a mobile phone from all over the world using the DTMF signaling. Traditionally wireless controlled vehicles make use of RF (radio frequency) circuits, which have its own disadvantages of restricted operational range, limited frequency range and limited control. Use of mobile phones for robotic controls provides working range as large as the coverage area of the service provider and no interference with other controllers. I can propose a microcontroller based less effort oriented, cost productive hockey ground roller with smooth pitch rolling technique operated from long range distance by using Mobile phone which acts as a DTMF signal controller with GSM technology. Generally the field of play is 91.4 by 55.0 meters with an area of 5,027 square meters for Hockey. According to my proposed work ground authority can be able to operate that roller to roll aforesaid measurement from pavilion without taking any help of ground staff. Combination of DTMF-GSM technology is more controller friendly as it doesn't interfere with other controllers and can use up to twelve controls. It also has the advantages of robust control and provides working range as large as the coverage area of the service provider.

In this paper, general information on the construction of tubular generators are given. Also, the numeric analyses were conducted by using 2D and 3D finite elements software. The output power, iron loss and cogging force change were compared by sensing the primary and secondary structural geometry of generator. Instead of the annular magnets, the magnets in the form of block were used mobile (secondary) part of generator. Also, analyses were conducted on the generator for two primary geometries.

This paper discusses about the approach towards effective power oscillation damping, root causes for the genesis of power oscillation and various methodologies adopted to eradicate it.This paper presents an unified approach of FACTS controller installation in order to ensure effective power oscillation damping. The power oscillations, if not controlled within time, may aggravate the entire power system's functioning and ultimate outcome as blackout. The network congestion has been a matter of serious concern to utility operations due to classical transmission corridors and inadequate controllers' deployment. The necessity of system regulations demands an adequate controller for matching the power requirement variability and this has been demonstrated with STATCOM control feature. This controller enhances the Available Transfer Capability along with security and reliability. IEEE 14 Bus system is simulated and studied with various scenarios with the help of MATLAB and PSAT to identify various complexities and to resolve these issues so as to enhance the ATC, reliability and security

Complete or partial blackout, poor power quality and damage to connected electrical pieces of equipment at the consumer end among others are day to day experience in Nigeria. One of the major causes of this scenario can be attributed to inability of electric power system to maintain a proper voltage level throughout the entire system. This paper addresses the problem of voltage violation on Nigerian 330kV, 24-bus grid system using shunt capacitor injection at defective buses. Newton-Raphson power flow solution method was use to carry out load flow analysis with and without shunt capacitor injection. The acceptable voltage limit ranges from 0.95 p.u to 1.05 p.u, voltage at bus 4, 9, 13, 14, 16 and 19 were found to fall below the minimum acceptable limit of 0.95 p.u, to improve the voltage at these buses a calculated amount of Mvar was injected at each buses respectively using the following capacitor sizes (110 Mvar, 3), (90Mvar, 26 ), (58Mvar, 17), (50 Mvar, 16), (38Mvar, 12) and (20Mvar, The study shows that the injected MVAr via shunt-type capacitors significantly improve the system voltage profile, voltage angles andthe total system losses before compensation was found to be 82.5982MWand after compensation the losses reduced drastically to 82.2826MW.
