The modern world depends on electricity. It’s a crucial resource, especially in urban areas, but electricity can’t be created, stored, and provided at a later time. The instant it’s produced, it’s used no matter how far apart the producer is from the user. And the infrastructure that makes all this possible is one of humanity’s most important and fascinating engineering achievements: the power grid.

This video continues the series on the power grid by diving deeper into the engineering of large-scale electricity generation. The importance of electricity in our modern world can hardly be overstated. What was a luxury a hundred years ago is now a critical component to the safety, prosperity, and well-being of nearly everyone. Generation is the first step electricity takes on its journey through the power grid, the gigantic machine that delivers energy to millions of people day in and day out. So how does it work?

This video explores the protective systems that keep the power grid from self destructing. We usually think of the power grid in terms of its visible parts: power plants, high-voltage lines, and substations. But, much of the complexity of power grid comes in how we protect it when things go wrong. When your power goes out, it’s easy to be frustrated at the inconvenience, but consider also being thankful that it probably means things are working as designed to protect the grid as a whole and ensure a speedy and cost-effective repair to the fault.

Discussing some of the fascinating engineering that goes into overhead electric power transmission lines. In the past, power generating plants were only able to serve their local areas. As power plants grew larger and further away from populated areas, the need for ways to efficiently move electricity over long distances has become more and more important. Stringing power lines across the landscape to connect cities to power plants may seem as simple as connecting an extension cord to an outlet, but the engineering behind these electric superhighways is more complicated and fascinating than you might think.

MOOC
Why are hybrid vehicles still more common than battery electric ones? Why are electric vehicles still more expensive than conventional or hybrid ones? In this course, you will get the answers to this and much more. While electric motors can improve vehicles regarding performance, energy consumption and emissions, they suffer from high cost and weight of batteries. Smart combinations of electric motors and combustion engines in a hybrid powertrain can combine these strengths with the advantages of combustion engines. This course is aimed at learners with a bachelor's degree or engineers in the automotive industry who need to develop their knowledge about hybridpowertrains. Inthis course, we willexamine different mechanical layouts of hybrid powertrains and how they influence the performance and complexity of the powertrain. Different sizing of powertrains in micro, mild, full hybrids, as well as plug-in hybrids, is also discussed and you'll learn how they can be modelled and analyzed for example by simulation of driving cycles. You will also learn about the Energy Management system and how this controls the hybrid powertrain modes and when to charge and discharge the battery. As a result of support from MathWorks, students will be granted access to MATLAB/Simulink for the duration of the course.

Electricity is generated at Lamma Power Station located at Po Lo Tsui of Lamma Island. The power station has a total installed capacity of 3,737MW made up of three 250MW coal-fired units, five 350MW coal-fired units, one 55MW gas turbines, four 125MW gas turbines, one 335MW combined cycle unit, one 345MW combined cycle unit, one 800kW wind turbine and one 1MW solar power system. Lamma Power Station provides a safe and reliable supply of electricity for more than 570,000 customers on Hong Kong Island and Lamma Island, and contributes to HK Electric’s world class reliability of more than 99.999%. Following the opening of Hong Kong's first wind power station, Lamma Winds, in 2006, an extension to the power station that burns the more environmentally friendly natural gas became operational the same year. In line with Government policy that aims to increase the use of gas, gas-fired generation has been increased to over 30% of the total output in 2010 when another gas-fired unit was put on use.
