abstract: In this paper we have developed a SCADA system for monitoring accessing the performance of parameter such as voltage, current, humidity on real time basis. For this we have used the infrastructure of the existing industrial network, which is based on plc, Supervisory Control and Data Acquisition (SCADA) is a field of constant development and research. This project investigates on creating an extremely low cost device which can be adapted to many different SCADA applications via some very basic programming, and plugging in the relevant peripherals. Much of the price in some expensive SCADA applications is a result of using specialized communication infrastructure. The application of infrastructure, in the proposed scheme the cost will come down. Additionally the generic nature of the device will be assured. A SCADA deals with the creation of an inexpensive, yet adaptable and easy to use SCADA device and infrastructure using the industrial network, in particular. The hardware components making up the device are relatively unsophisticated, yet the custom written software makes it re programmable over the air, and able to provide a given SCADA application with the ability to send and receive control and data signals at any non predetermined time. From the SCADA system which is proposed in setup the battery voltage of 12v could be sufficiently recorded from remote location. The properly designed SCADA system saves time and money by eliminating the need of service personal to visit each site for inspection, data collection /logging or make adjustments. Main concept of our paper is data acquisition controlling by using SCADA software and PLC. Here PLC is a medium between electrical system Personal Computer for SCADA to take input and output bits. Automating electrical distributions systems by implementing a supervisory control and data acquisition (SCADA) system is the one of the most cost effective solutions for improving reliability, increasing utilization, increasing efficiency and saving costs. Nowadays consumer requires more reliable efficient power supply. So we can use automation systems as per the consumer

title: Renewable Energy (Solar Power) Mini Prototype Plant With Scada System
year: 2010

abstract: The former Research Institute for Sustainable Energy (RISE) testing laboratory was originally a facility for measuring, monitoring and testing a variety of renewable energy systems. The RISE facility was independent of the School of Engineering and Energy, but has recently been taken over by the School as the Engineering and Energy Laboratory. Many of the systems associated with the laboratory have not been operated for a number of years and the condition of these systems, and the equipment that is associated with them, is not known. Personnel involved with the former RISE facility have since left Murdoch taking with them their knowledge of the facility. This project was primarily concerned with re commissioning these systems and developing an operational knowledge of the SCADA based control system. Areas to be covered in particular were: connections to the grid from PV arrays and wind turbines PLC system and software inverters, solar array simulator, environmental chamber and other peripheral equipment power supplies such as the diesel generator, motor generator set and battery banks 3 phase permanently connected power monitors AC and DC electrical systems Initial inspections of the electrical systems showed that two key components of the facility were found to be defective and would need to be rectified if the facility was to function properly. These components were the diesel generator which provided electricity totally independent of the grid for testing purposes, and a fault on the PLC which was affecting the operation of the electrical systems. Also several main pieces of equipment had since been removed from the facility; most notably of these being the battery banks, main test inverter and the DC supply from the wind turbines located in what is now known as the Renewable Energy Outdoor Test Area (ROTA) Several pieces of equipment required for the operation of the diesel generator would also require attention such as the fuel tank and starting battery. Approval was granted for the alternator to be repaired and placed back into service. Approval was also granted for the purchase of a replacement analogue input card to rectify the fault with the PLC. In addition to this another requirement of the project was to develop a system so that the laboratory could be used as a training facility for future students. A procedure was developed so that an electrical system consisting of actual real components; a source, a transmission and distribution system and a load could be simulated. Software was also developed using National Instruments LabVIEW software to monitor and record various power parameters from the system. The system is referred to as the "Small Electrical Distribution System" As an aside to this a program has been developed that monitors and records voltage, current and power that is being produced by the Real PV Array located on the roof of the Energy and Engineering Laboratory building. For someone who is unfamiliar with the setup of the electrical systems that make up the Energy and Engineering Laboratory a simplified block diagram of the Main AC switchboard has been produced. Schedules have been included of all socket inlets and outlets, main AC and communications cables and the Main AC Switchboard nomenclature. The diesel generator is nearly ready to be re commissioned after approximately 5 years of non use. Procedures have been developed so that a user can configure the Main AC switchboard so that the "Small Electrical Distribution System" can be operated safely and measurements obtained and analysed. The main goal of the project was to get the diesel generator operating; therefore this report is focused on the equipment associated with the diesel generator. The equipment focused on was the diesel generator itself, the Main AC Switchboard, the Load Bank and the PLC system. Systems such as the Main DC switchboard and Solar Array Simulator were not covered in as much detail as they are not required for the "Small Electrical Distribution System"

abstract: Non renewable energy is a relatively short term energy source; consequently, the uses of alternative sources such as solar energy are becoming more wide spread. To make solar energy more viable, the efficiency of solar array systems must be maximized. A feasible approach to maximizing the efficiency of solar array systems is sun tracking.PV modules are devices that cleanly convert sunlight into electricity and offer a practical solution to the problem of power generation in remote areas. The Sun Tracking system using PLC designed offers a reliable and affordable method of aligning a PV module with the sun in order to maximize its energy output.Design of Sun Tracking system using PLC is a hybrid hardware/software prototype, and consists of SCADA system which automatically provides best alignment of PV panel with the sun, to get maximum output (electricity) with monitoring the system by controlling the movement with Programmable Logic Controller (PLC) and minimizing the loss of energy that is applied for the control system.By applying the proposed technique it is expected that the efficiency of the PV plant will maximize.

abstract: Development of a solar powered irrigation system has been discussed in this paper. This system would be SCADA based and quite useful in areas where there is plenty of sunshine but insufficient water to carry out farming activities, such as rubber plantation, strawberry plantation, or any plantation, that requires frequent watering. The system is powered by solar system as a renewable energy which uses solar panel module to convert Sunlight into electricity. The development and implementation of an automated SCADA controlled system that uses PLC as a controller is significant to agricultural, oil and gas monitoring and control purpose purposes. In addition, the system is powered by an intelligent solar system in which solar panel targets the radiation from the Sun. Other than that, the solar system has reduced energy cost as well as pollution. The system is equipped with four input sensors; two soil moisture sensors, two level detection sensors. Soil moisture sensor measures the humidity of the soil, whereas the level detection sensors detect the level of water in the tank. The output sides consist of two solenoid valves, which are controlled respectively by two moistures sensors.
