Mobile robot for power substation inspection: a survey

Improvement of substation Monitoring aimed to improve its efficiency with the help of Big Data Analysis**

“…To the knowledge of authors Lu S USES first used Big data and cloud computing for the monitoring of substation. While understanding the existing infrastructure and model Lu has developed a data center, and provided a better cloud computing based solution for the state monitoring of substation, this model was helpful for the analysis of smart grid also [11]. Xie X J has made it evident that the existing system is the limited in its application and wont be able to handle the huge amount of data generated by modern substation and smart grid networks.…”

“…This dependency over the electricity required a robust electric distribution and generation system, which should have a minimum failure rate. To ensure that and to avoid power outages, transmission lines and electrical substation (referred as substation hereafter) equipment must be periodically monitored and precautionary measures should be taken to avoid any fault [2,3]. In particular the role of substation become vital in that and efforts to make it smart and technology driven is a need of today's Power system.…”

The Operation of UAV Propulsion Motors in the Presence of High External Magnetic Fields

“…Regular operation and maintenance (O&M) is an essential component of windfarm efficacy but is costly; it is generally acknowledged that offshore wind farms' O&M expense is significantly higher than that of onshore farms, largely caused by the high cost of offshore sites visits and repair by trained personnel [2]. To reduce this cost robotic inspection systems are being developed [3][4][5] which can provide improved accessibility and human safety offshore.…”

Cloud-Edge Fusion Based Abnormal Object Detection of Power Transmission Lines Using Incremental Learning

“…Many factors, such as abnormal events (e.g., mountain fires/smokes) and artificial destruction (e.g., by a working engineering machinery), can threaten the security of grid infrastructures [1] (see FIGURE 1). When high voltage transmission lines are longer and more dispersed, traveling through complicated terrain conditions (e.g., mountains), it becomes more difficult to continually monitor transmission lines for abnormal object detection via human, mobile robots [2] or helicopters, as it involves extensive labor efforts and high startup and maintanence cost.…”
