WIRELESS POWER THEFT MONITORING SYSTEM
Power larceny is the sizably voluminous quandary now days which causes immensely colossal loss to electricity boards. And to surmount these losses prices are incremented. So if we can obviate this larceny we can preserve lots of potency. The mundane practice for power larceny is to short input output terminals or to place magnet on the wheel in case of old meters. In this system a micro controller is interfaced with an energy metering circuit current sensing circuit, RF communication & a contactor to make or break power line. If current is drawing & energy pulses are mundane then no puissance is larceny. If current is drawing & energy pulses are not coming then it designates power larceny. So microcontroller trip the o/p utilizing relay. This information is sent to substation utilizing wireless communication. Line faults may be caused due to over current or earth fault. If there transpires to be a connection between two phase lines then over current fault occurs. Earth fault occurs due to the earthing of phase line through cross arm or any other way.

Power line carrier communication (plcc)
PLCC uses high voltage transmission lines to transmit speech, telemetry, and protection commands between substations in a cost effective and reliable way. The signals are modulated onto a carrier frequency between 40-500kHz and injected onto the line through coupling capacitors. Line traps allow the signals to pass through but prevent them from entering the substations. The technology provides communication without additional wiring by using the existing power infrastructure.
Types of Irrigation
1. Irrigation is the artificial supply of water to crops through methods like surface, sprinkler, and drip irrigation. Surface irrigation involves distributing water over the soil surface by gravity in techniques like basin, border, and furrow irrigation.
2. Sprinkler irrigation applies water similar to rainfall through pipes and sprinklers. Drip irrigation drips water slowly from pipes and emitters directly to plant roots.
3. The suitable irrigation method depends on factors like soil type, crop type, technology, costs and previous experience. Surface irrigation is common on loamy and clay soils while sprinkler and drip are more suitable for sandy soils with low water storage.

Automatic energy meter reading
This document discusses automatic meter reading (AMR) systems. AMR allows meter readings to be collected remotely via telecommunication links rather than manual readings. Two common communication methods are powerline carrier communication (PLCC) and GSM. PLCC uses existing power lines to transmit data while GSM utilizes mobile networks. The document describes traditional electromechanical meters and advantages of automated digital meters. It also provides an overview of how AMR systems work including the use of encoder-receiver-transmitters connected to meters and data concentrator units that collect readings over PLCC. AMR allows more accurate billing and monitoring while reducing costs compared to manual meter reading.

This document summarizes a research paper that proposes a novel low-cost WAMPAC system for power network monitoring and control. The system uses data sampling units to measure voltage, current, and frequency from distribution feeders. A data concentrator unit timestamps the measurements using a GPS module and stores them in a database. A master controller provides remote monitoring and control via wireless communication. Various protection schemes like distance, overcurrent, differential and synchronizing are implemented for feeder protection and coordinated between the feeder and master controllers. The proposed low-cost design aims to provide reliable monitoring and protection at an affordable price for all power sectors.

This document summarizes research analyzing the performance of an iterative IDMA (interleave division multiple access) scheme for power line communication. The IDMA model simulated uses BPSK modulation with k simultaneous users on a single-path power line channel. Convolution coding with a rate of 1/2 was used at the transmitter. Simulation results showed that increasing the data length and using coding improved the bit error rate performance of the IDMA system over power line channels. Coded IDMA achieved a lower bit error rate than uncoded IDMA.

35_ELECTRICAL POWER
The document describes an electrical power theft detection and wireless meter reading system. The system uses wireless data transmission between digital energy meters and a pole-mounted receiver to detect discrepancies between the power sent on a distribution line and the power consumed by loads on that line, indicating potential theft. It also allows for wireless meter reading to save utility companies time compared to manual readings. If the power measured at the pole exceeds the consumption measured by a load-side meter by more than a set tolerance, factoring in line losses, theft is detected on that line.

The document describes the LRR (Line Reflect Reflect) technique, a new self-calibration procedure for calibrating vector network analyzers (VNAs). VNAs measure the complex transmission and reflection characteristics of microwave devices. The LRR calibration circuits consist of line elements and a symmetrical reflection standard placed at three consecutive positions. During calibration, the systematic errors of the VNA are eliminated to determine the unknown line and obstacle parameters. The LRR technique provides advantages like simplifying test fixtures and improving accuracy. The calibration structures can be easily realized using microstrip technology.
Plc presentation.
This document discusses power line communication (PLC) and transmission impairments. It provides an overview of PLC including its features, technical aspects, and applications. It then discusses two main transmission impairments: excessive noise levels from household appliances that can interfere with data transmission, and cable attenuation as devices are connected and disconnected from the power network. The document proposes two solutions to minimize these issues: using a type M-1877 noise suppression network to reduce high frequency emissions, and an adaptive network solution using low density parity-check and signal-to-noise ratio algorithms to allow for error correction with small packet sizes.
Differential equation fault location algorithm with harmonic effects in power...
About 80% of faults in the power system distribution are earth faults. Studies to find effective methods to identify and locate faults in distribution networks are still relevant, in addition to the presence of harmonic signals that distort waves and create deviations in the power system that can cause many problems to the protection relay. This study focuses on a single line-to-ground (SLG) fault location algorithm in a power system distribution network based on fundamental frequency measured using the differential equation method. The developed algorithm considers the presence of harmonics components in the simulation network. In this study, several filters were tested to obtain the lowest fault location error to reduce the effect of harmonic components on the developed fault location algorithm. The network model is simulated using the alternate transients program (ATP)Draw simulation program. Several fault scenarios have been implemented during the simulation, such as fault resistance, fault distance, and fault inception angle. The final results show that the proposed algorithm can estimate the fault distance successfully with an acceptable fault location error. Based on the simulation results, the differential equation continuous wavelet technique (CWT) filter-based algorithm produced an accurate fault location result with a mean average error (MAE) of less than 5%.
