Uninterruptible Power Supply

In the United Kingdom over the past half century, the use of electricity has been increasing year on year (Figure 1). This increase in demand means that the supply of electricity is becoming more critical to the consumer and how much everyday life requires the use of electricity. Disruption to the supply can cause major issues and potential financial difficulty to many consumers who require a constant supply. Electricity disturbances can come in many different arrangements which affect the AC waveform and influence electrical loads in different ways. Common disturbances are shown in Figure 2 Depending on the criticality of the load devices can be placed between the supply and the load to eliminate these issues. Common devices used to eliminate disturbances are Uninterruptible power supplies Power Filters/Conditioners Different UPS systems can be used to eliminate disturbances through different configurations and setups. Power conditioners operate to illuminate certain aspects of the disturbances but won’t eliminate disturbances like interruptions UPS systems can incorporate power conditioners to eliminate all these common disturbances to help give a constant supply for consumers. 1.1 Aims The principle aim of this final year individual project is to design and build an Uninterruptible Power Supply to eliminate interruptions up to 5 minutes. On failure of the supply, the system will pick up the load and continue to provide power until the main supply has returned after 5 minutes 1.2 Objectives Research and develop an understand of existing UPS configurations Design and build a standby UPS system including An AC to DC rectifier to supply an input to a DC Buck Charger A DC to DC converter to reduce input voltage to charge retrospective batteries A DC to AC inverter to make an AC voltage of 24V RMS An AC to AC converter to transfer between the duty and standby supply Develop an Arduino interface to control and display UPS parameters including Control of the switching of the DC to AC inverter Control of the AC to AC transfer switch Manual Control of UPS Display of UPS circuit position Voltage parameter readings for AC and DC AC load current and voltage readings Battery Temperature readings Evaluate UPS and discuss further work 1.3 Motivation The motivation for this final year project has come from time spent on placement at Phillip66 Humber Refinery working on the maintenance of primarily double conversion and rotary UPS systems. Through this experience, it has given an understanding of the systems and an interest to design and build a UPS. 2.1 UPS Configurations An uninterruptible Power supply is a system designed to maintain power or provide power when the input power fails or is disrupted. A UPS can be designed as a DC or AC back up, but most common UPS systems in the UK are designed to give AC because this is how electricity is supplied through the grid. [3] An AC UPS output can be produced using either a rotating machine (Rotary UPS) or a semiconductor based inverter (Static UPS). Batteries are the main energy source for both systems but for rotary systems, other rotating energy sources can be used. The UPS configurations as shown in Table 1 shows the different arrangements of a UPS 2.2 UPS Operation 2.2.1 Rotary UPS The rotary UPS generally consists of a motor and generator set but how these are configured depends on of the type of rotary UPS. Fixed Flywheel UPS (Figure 3a) [3] [4] Mains electricity operates an AC motor that is connected through a specially designed flywheel to an AC generator to produce an AC output. While the motor is driving the generator the flywheel rotates which stores kinetic energy. When the main supply fails the kinetic energy in the flywheel continues to turn the generator for a short duration until another supply is provided by a backup generator.

Crude Oil as a Global Commodity: Logistics

assignment writer Transportation of the Crude Oil Nowadays, due to globalization, the world community needs to master the most effective ways of the transportation of global commodities. There are four primary methods that are used to transport crude oil, namely, pipeline, boat, truck, and rail (Steer, 2018). Pipelines remain the most efficient way to transport petroleum as modern technologies allow people to track its ways and prevent leaks and pipeline bursts. Pipelines are usually made of stainless steel and are buried deep underground. The utilization of pipelines brings both positive and negative consequences. Thus, it ensures the transportation of crude oil to various parts of the world but destroys natural sceneries in places where they are installed. Sometimes, it might be difficult to transfer the crude oil through pipelines as not all the countries have an opportunity to install them on their territory. For example, it may be challenging for coastal countries to bury pipelines under the water. In this case, boats are used for the transportation of oil over the ocean. As a result, petroleum-producing countries have an opportunity to carry large quantities of oil using giant ships. However, at times, the shipwrecks occur, which result in the crude oil offshore and seawater pollution. Trucks are usually used to carry oil for close-range distances, such as to local business companies. This transportation means is not popular for international shipment as it cannot carry a large quantity of oil. However, if an accident occurs, it is easier to clean up the oil on the road rather than in the sea. As for rails, they can also be used for carrying the oil to remote destinations. Moreover, the total volume of oil lost during transportation by rail is less than in other transportation methods (Steer, 2018). Nevertheless, some scholars still assert that pipelines are found to be a much safer transportation method than rails (Green,

Antioch Unified School District Essay

Table of Contents Introduction Readiness and Emergence Response in the District Conclusion References Introduction Antioch Unified School District is one of the biggest school districts in the state of California. It is comprised of elementary schools and high schools. The school district serves more than 19000 students in the city of Antioch, California (AUSD, 2011). With the high population of this school district, it is necessary to have an effective and efficient disaster management programme to ensure the safety of students while at school. To achieve this, the school district has come up with a number of programmes which ensure that all the schools in the district are well prepared in case an emergency occurs. These programmes have been working well and in the year 2010 the school district received a grant from the Department of Homeland Security to improve on its project (AUSD, 2011). Readiness and Emergence Response in the District Antioch Unified School District is one of the most successful school districts in the United States which has shown a lot of progress in emergency readiness and response. It has a number of programmes that have made the school staff, students, parents, guardians and other community members to be well prepared in case disasters strikes. These programmes include: prevention, preparedness, response and recovery (U.S Department of Education, 2010). This ensures that all students are safe while they are at school. These programmes have been effective in the control and prevention of drug and alcohol abuse, crime control and other gang related activities. They also support the well being of students, creation of safe environments in schools and promotion of programmes which teach the students to have desirable characters and be good and responsible students in future. To achieve this, the school district has collaborated with local law enforcers, social institutions, parents and guardians. They work together as a team to ensure that all these goals and objectives are achieved. This has been very effective since it ensures that students are safe whether they are in school or not. To be ready for disasters, the school district has a number of facilities and equipments. The facilities which the school district has include: technology support, education technology, data systems, system support and maintenance and operations. It has also implemented several policies and guidelines which have to be followed by all the schools in the district. Furthermore, the school district has formulated a plan for readiness and preparedness management for schools (REMS). The plan has several goals, objectives and activities which ensure that the school district is well prepared. Formation of C-REMS, school site safety plan and training are the goals of this plant. Get your 100% original paper on any topic done in as little as 3 hours Learn More The plant is working well since all the schools in the district have understood and can implement emergency basics such as in the event of fire, disease outbreak and so on. However, there are some improvements which need to be conducted to ensure the efficiency of the programme. The amendments include: provision of up to date machinery and equipments, intense training of teachers, students, parents and guardians and the formulation of an efficient communication method in times of emergency for an efficient reunification process. Due to these needs the school district requires more money to fund new projects and improve on the ones. This will ensure that the success of the projects will continue to perpetuity due to the sustainability of the projects. The government should therefore give the school district grants to keep the projects going. Conclusion The emergency and response projects of Antioch Unified School District have been successful. The proper planning, dedication and executions of these projects should be credited for this success. However, there are some improvements which need to be done to ensure that the projects become more effective and efficient. That is why the school district is applying for a grant from the government in order to get funds to run and manage the projects. References AUSD (2011). District at a Glance. Antioch.
