Incorporating information and communication technologies into grid systems provides advanced capabilitiesfor remote, and real-time monitoring and control of devices. In smart grid systems, wireless relays are used inthe data collection for fault detection and power quality analysis. When wireless base stations are closer to highvoltage transmission lines, the signals from the base stations impact the monitoring of the lines as impulsivenoise. With the growing number of cellular base stations mainly in urban areas, this impulsive noise becomes aproblem causing the loss of data integrity when wirelessly transmitted. In this project, we will study thisproblem to quantify the loss of data and to determine the number of additional relays required to maintain thesame data quality in this noisy environment. This will help optimize the relay system operations (number ofrelays and locations) when excessive noise is detected in power lines.In particular, a hybrid network architecture comprised of wireless sensor networks and cellular network will beconsidered to monitor the high voltage transmission lines in the urban and suburban areas. Corona noise is oneof the sources of electromagnetic interference in such lines. We will first characterize the wireless channel withimpulsive Corona noise near cellular base stations; then formulate and solve the problem of finding theoptimum number of relays/sensors in a Zigbee-based linear and non-linear wireless sensor networks. Goal is todevelop a matrix with the expected number of additional relays and their locations needed to maintain the samedata quality for various intensity of noise level. The effects of physical and MAC layer parameters on themonitoring performance will also be quantified and included in the matrix to be used as operational guidelinesin the relay system.

将信息和通信技术纳入网格系统中，为远程和实时监视和控制设备提供了高级功能。在智能网格系统中，无线继电器用于数据收集中，以进行故障检测和功率质量分析。当无线基站更接近高压传输线时，基地的信号会影响线路的监视为脉冲。随着蜂窝基站的数量越来越多，主要是在城市地区，这种冲动的噪声变成了无线传输时数据完整性丧失的问题。在这个项目中，我们将研究本问题，以量化数据丢失，并确定在这个嘈杂的环境中维持这些数据质量所需的其他继电器数量。当在电源线中检测到过多的噪声时，这将有助于优化继电器系统操作（数量和位置的数量）。尤其是，由无线传感器网络组成的混合网络体系结构和蜂窝网络将受到监视以监视城市和郊区区域中高压传输线。电晕噪声是此类电磁干扰来源的一种。我们将首先对无线通道进行表征，并在蜂窝基站附近带有电动的电晕噪声。然后制定并解决在基于Zigbee的线性和非线性无线传感器网络中查找接力/传感器数量的问题。目标是矩阵的矩阵，其预期的其他继电器数量及其位置，以维持各种噪声水平的Samedata质量。物理和MAC层参数对InterInitoring性能的影响也将被量化并包含在矩阵中，以用作继电器系统的操作指南。
