Power System Data Application Based on Data Association Rules

With the continuous development and progress of society, electricity has been integrated into people’s lives. However, power transmission is a very complex process that requires power transmission and power system conversion. A large amount of data will be generated during the operation of the power system. Through these data, we can use electricity better and more efficiently. This paper aims to study the power system data application based on data association rules. Based on the analysis of data association rules related algorithms and the application of data association algorithms in the power system, a power failure prediction system is designed and the performance of the system is analyzed. The test results show that the system has a very high transaction success rate, the longest response time does not exceed 20 seconds, and the CPU is operating normally, reaching the expected expectations.

Smart Incubator for Preterm Neonatal Using Kangaroo Mother Care

Kangaroo mother care is an apparatus that provides closed and controlled environmental for the preterm babies. A Preterm birth is commonly defined as any birth base 37 weeks completed weeks of gestation period. This paper deals with cost effective design of incubator that monitors parameters like pulse rate, temperature, humidity, child security and the readings will be continuously displayed In the LED screen and also monitoring the details to the corresponding doctor, nurse and parents by using GSM. The power failure problem is also eliminated by using solar panel. We also intimate the parents about feeding time, dressing time, ear check, eye check. But many of the existing system does not mentioned about above problem and have adopted only with humidity and temperature and also by manual control. So the main objective of this research is to overcome drawbacks and provide eco friendly service to all common people.

Identification of defected sensors in an array of amperometric gas sensors

Purpose Amperometric gas sensors are commonly used in air quality monitoring in long-term measurements. Baseline shift of sensor responses and power failure may occur over time, which is an obstacle for reliable operation of the entire system. The purpose of this study is to check the possibility of using PCA method to detect defected samples, identify faulty sensor and correct the responses of the sensor identified as faulty. Design/methodology/approach In this work, the authors present the results obtained with six amperometric sensors. An array of sensors was exposed to sulfur dioxide at the following concentrations: 0 ppm (synthetic air), 50 ppb, 100 ppb, 250 ppb, 500 ppb and 1000 ppb. The damage simulation consisted in adding to the sensor response a value of 0.05 and 0.1 µA and replacing the responses of one of sensors with a constant value of 0 and 0.15 µA. Sensor validity index was used to identify a damaged sensor in the matrix, and its responses were corrected via iteration method. Findings The results show that the methods used in this work can be potentially applied to detect faulty sensor responses. In the case of simulation of damage by baseline shift, it was possible to achieve 100% accuracy in damage detection and identification of the damaged sensor. The method was not very successful in simulating faults by replacing the sensor response with a value of 0 µA, due to the fact that the sensors mostly gave responses close to 0 µA, as long as they did not detect SO2 concentrations below 250 ppb and the failure was treated as a correct response. Originality/value This work was inspired by methods of simulating the most common failures that occurs in amperometric gas sensors. For this purpose, simulations of the baseline shift and faults related to a power failure or a decrease in sensitivity were performed.

Construction Planning and Operation of Battery Swapping Stations for Electric Vehicles: A Literature Review

The popularity of electric vehicles has been limited by factors such as range, long charging times and fast power failure in winter. In order to overcome these challenges, battery swapping stations (BSS) have been constructed and greatly promoted in recent years. In this paper, the related literature on electric vehicle service is reviewed and the co-occurrence of keywords is analyzed using CiteSpace. The literature is classified according to clustering results and recurring themes, such as the location of BSS, inventory decisions, charging strategies and BSS assignment. In each topic, typical optimization models and algorithms proposed in previous studies are summarized. Then, this paper gives a case about the business model and revenue capacity calculation of BSS. Finally, it points out the future research direction of battery swapping stations for electric vehicles.

Technical Research on Substation Overhaul Status Based on the Combination of Computer Technology in Power System

This article mainly focuses on the technical analysis of the substation overhaul status and the application of substation overhaul technology in the power system.

Perception and Use of OPAC by Users in Academic Libraries in Kwara State, Nigeria

Background of the study: The study investigated the use and perception of Online Public Catalogue (OPAC) by users in academic libraries in Kwara State, Nigeria. Purpose: The study adopted descriptive survey research method were a total number of 203 questionnaires were distributed amongst library users in both selected academic libraries. A simple random sampling technique was used for this study. Method: The descriptive analysis was used to analyze the collected data using frequency counts and simple percentages. Findings: The study revealed that majority of the respondents is aware of the existence and availability of OPAC. Although a very small percent of respondents in Unilorin and Kwara State Polytechnic got their awareness of OPAC through the library. The study also revealed that an average percent of respondents in both institutions can make use of the library OPAC effectively. Based on user’s perception of OPAC, the findings show that majority of respondents highly acknowledge OPAC, well perceived and more preferred to card catalogue. A high percent of respondents admitted that the library OPAC enable them to locate materials quickly on the shelf. However, most of the respondents showed that they are facing some challenges which include poor network services, power failure, poor assistance from the library staff etc. Conclusion: The researchers recommend that the library should create more awareness and effective user education for students on the use of OPAC at various levels to ensure maximum utilization of the library resources.

Research on Optimization of Power Emergency Material Dispatching for Beijing Winter Olympics

The Beijing Winter Olympic Games is an extremely important event, and the supply of electricity is the basis for it. In order to prevent the sudden loss of power to the event, it is necessary to carry out power repair and restore normal power supply in the shortest possible time. Contemporary research is less focused on the emergency repair of power systems. This thesis studies the dispatching of power emergency materials in two stages and in the first stage, the minimum gap rate and the shortest time for material dispatching and transportation are mainly considered, and the required types of power emergency materials are dispatched from the storage near the Olympic venues to various power failure points. In the second stage, aiming at the shortage of power emergency materials at each fault point, the power emergency materials will be dispatched from the rear national power grid regional material reserve to the power emergency materials reserve near the Olympic venues and then dispatched to each power fault point through the power emergency materials reserve. Finally, this paper verifies the effectiveness of the combination of the primary and secondary dispatching models in an example, providing a reference for further improving the emergency response capability of the Olympic venues and improving the safety system of the power system.
