In the context of power system, Static Synchronous Compensator (STATCOM) plays an important role to compensate stored energy in reactive elements. Lately, researchers are working for the selection of better optimized feedback Controller gains for the STATCOM control input. This paper presents a systematic approach for selecting such an optimized feedback control input, by considering the system with and without disturbances. Optimized control input models presented here is tested on the Single Machine Infinite Bus (SMIB) linearised Phillips-Heffron model of a power system installed with STATCOM using MATLAB/SIMULINK platform for damping oscillations.
Nowadays, the growth of Module Integrated Converters (MIC) concept is going on increasing. This concept was developed for Photovoltaic (PV) applications to improve the efficiency of the converters. In this paper, the authors have proposed a submodule Maximum Power Point (MPP) tracking algorithm to track the maximum power from the partially shaded cells. Generally, PV module have three submodules. Each submodule is formed by series connection of two strings. Here a different Perturb and Observe (P & O) algorithm is considered for each submodule to track maximum power from the all three submodules. Each submodule will have their own DC-DC converter. In Direct Current (DC) stage, DC-DC converters are connected in three configurations to serve sufficient energy to inverter for single phase grid connected systems.
Supervisory Control and Data Acquisition (SCADA) systems are widely used to automate monitoring and control of substations. Technologies such as high-speed wide area networks, Transmission Control Protocol (TCP)/ Internet Protocol (IP), switched Ethernet and high-performance low-cost computers prove to be potentially promising for increasing reliability and fostering high speed communications within the sub-station. In order to boost interoperability between Intelligent Electronic Devices (IEDs), International Electro-technical Commission’s (IEC) 61850 communication protocol has been established. With this protocol, the devices communicate with each other, thereby simplifying communication issues which were prominent in legacy substation automation protocols. A digital power grid can thus be created by implementing protection schemes modeled with communication configurations with standardized information exchange. As a result, the demand for a Substation Automation System (SAS) which provides high performance, flexibility and is simple to integrate has been fulfilled by means of IEC 61850 communication protocol.
As technology changes, automation plays an important role in handling the systems. After the invention of the wheel, various types of vehicles were introduced. The internal combustion engines run on liquid fuel, which should be very efficient from the economic point of view as day-by-day, the fuel becomes very expensive. For proper indication of the fuel, the entire vehicle has a smart fuel indication system, which is inbuilt into the vehicles. Without this smart fuel indicator, the oil distributor trying to cheat while filling the fuel tank at the fuel station. In this paper, the authors proposed a method by which we can continuously monitor the fuel level of the vehicle before filling the fuel and after filling the fuel.
Nowadays, automation plays a very important role in the market both in domestic and industrial purposes. In this paper, devices are gathered in such a way that it can sense the fire and do necessary actions after that. This automatic fire control system works without human effort. Due to the change in the recent technologies day by day, the robotics have gained a specific position. Nowadays in every work, automation plays a very crucial role. One of the necessities is designed in this work. In this paper, the authors have proposed a prototype to fight against fire, i.e. “firefighting robot”.
