IoE-Based Control and Monitoring of Electrical Grids

In many countries, renewable energy production already represents an important percentage of the total energy that is generated in electrical grids. In order to reach higher levels of integration, demand side management measures are yet required. In fact, different from the legacy electrical grids, where at any given instant the generation levels are adjusted to meet the demand, when using renewable energy sources, the demand must be adapted in accordance with the generation levels, since these cannot be controlled. In order to alleviate users from the burden of individual control of each appliance, energy management systems (EMSs) have to be developed to both monitor the generation and consumption patterns and to control electrical appliances. In this context, the main contribution of this chapter is to present the implementation of such an IoT-based monitoring and control system for microgrids, capable of supporting the development of an EMS.

IT SERVICE OF THE MODERNIZED GRAIN MOISTURIZING MACHINE

The purpose of this work is to increase the efficiency of the grain humidifier, which is part of the system for preparing grain for grinding, ensuring the reliability of machines, its productivity, reducing energy consumption and improving the quality of the finished product. products by introducing automation based on SMART technology, defined as self-monitoring and reporting technology.SMART technology is inextricably linked with a monitoring and data collection system designed to monitor and automatically manage a large number of remote, geographically dispersed sites. In addition, this system provides long-term archiving of the received data, which allows the dispatcher to monitor the operation of the relevant equipment, responding with an IT service program.A remote automated monitoring and control system for the production line on which the dampening machine is installed ensures optimum performance. Rotary machines for grain moistening are considered. At flour mills, as well as at other enterprises, such machines are used at the stage of main moistening and for additional moistening before feeding the grain to the grinding workshop. A1-BShU-2 machines are designed for basic grain moistening.Humidifiers are installed in front of the grain bins in the production lines of the preparatory departments of flour mills to remove excess moisture.At the same time, machines for washing grain and, accordingly, all equipment for treating wastewater and treated waste can be excluded from the technological schemes of enterprises, therefore, an urgent task is to increase productivity. Air humidifier A1-BShU-2 by improving the design of the working body and automation of the machine. generally.In this regard, it is necessary to intensify the process of moistening the grain due to the optimal location of the blades for moving the grain (races) and mixing (whips) on the shaft of the working body, apply a drive motor speed control system using a frequency converter.The article shows ways to improve the performance of a humidifier, as well as issues of control and management of the optimal mode of its operation. For example, Table 1 is presented in the form of a layout, which shows in what form the information can be provided to the operator and stored in the archive.

DESIGN OF COMPLETELY AUTOMATIC ODMCS

This paper presents a novel approach for designing a completely automatic Oil Discharge Monitoring and Control System (ODMCS) for the discharge of oily mixtures/effluents from cargo area and slop tank of oil tankers. The Global Positioning System (GPS) and modified World Vector Shorelines (WVS) data are used for the development of a system, which completely automates the working of ODMCS to comply with Marine Pollution (MARPOL) regulations. The system level hardware and software design for the same is discussed. An animated simulator for the completely automatic ODMCS is developed. The developed system may also be used as ODMCS emulator when main ODMCS fails. The results obtained by applying the test inputs to such a system have been presented and verified against the requirements of MARPOL regulations.

Approach to Nav Aids System on Islands

Offshore business is gradually moving from traditional Well Head Platforms to the concept of Artificial Drill Islands and use of renewable energy sources. Navigational Aids design for artificial drilling islands has unique challenges due to vast periphery. This paper highlights all such challenges along with recommendations for a reliable and cost effective solution. Clients as well as FEED/EPC Contractors can benefit from the experience shared in this paper. The trend over the last decade has been to develop Navigation Aids that minimize maintenance requirements whilst maintaining stable and satisfactory performance. Although, Navigation Aids are automated there is still a need for regular visual inspections as there is always the risk of vandalism, ship impact or damage during significant storm events. Navigational Aids System shall be in strict compliance with International Association of Lighthouse Authorities (IALA) Guidelines. In addition to usual Visual & Audible Navigations Aids, artificial islands require break water lanterns (both red & green type). Also, number of Navigational Aids is much more than those required for a typical offshore platform. Requirement of interfaces with remote ends need to be clearly defined as these have impact on the design and ultimate cost. GSM monitoring and control system, GPS synchronization & AIS remote monitoring shall be considered. Cabling over the Island periphery is neither reliable nor cost effective solution. Standalone solar power based Navigational Aids Skids with all control and monitoring facilities can be more suitable solution. Considering that Island Contractor provides few Navigational Aids before the mobilization of EPC Contractor, it is essential to coordinate the Navigational Aids design aspects to ensure synergy in terms of compatibility.

A Novel System-Theoretic Matrix-Based Approach to Analysing Safety and Security of Cyber-Physical Systems

Cyber-Physical Systems (CPSs) are getting increasingly complex and interconnected. Consequently, their inherent safety risks and security risks are so intertwined that the conventional analysis approaches which address them separately may be rendered inadequate. STPA (Systems-Theoretic Process Analysis) is a top-down hazard analysis technique that has been incorporated into several recently proposed integrated Safety and Security (S&S) analysis methods. This paper presents a novel methodology that leverages not only STPA, but also custom matrices to ensure a more comprehensive S&S analysis. The proposed methodology is demonstrated using a case study of particular commercial cloud-based monitoring and control system for residential energy storage systems.

IoT Enabled Ventilator Monitoring System for Covid-19 Patients

The use of the IoT protocol on medical equipment is expected to provide protection for medical personnel in dealing with Covid-19 patients, especially when medical personnel are monitoring and setting up an equipment. This study aims to (1) produce a monitoring and control system for a breathing apparatus (Ventilator) based on the Internet of Thing (IoT), (2) test the ventilator control function, (3) test the data transmission function with the IoT protocol. The method used is Define, Design, Develop, and Disseminate (4D). Data collection is done through (1) Testing and Observation (2) Limited field test. This research produces a control and monitoring system for mechanical ventilators. The mechanical ventilator consists of a gripper motion mechanism driven by a dc motor. The movement of the gripper creates pressure and releases pressure on the ambu bag. The depth of pressure exerted by the gripper is measured as the volume and pressure of the air delivered to the lungs. The rate of pressure exerted is measured as the velocity of air flowing into the lungs.
