ElectricalWorld - Incorporating Electrical Engineer

JA Solar Holdings Co., Ltd. one of the world’s largest manufacturers of high-performance solar power products, has announced its PV modules have passed the high-grade Class 4 Hail Test conducted by RETC in May at its facility located at Fremont, California , following the successful pass of the similar test conducted by TUV Rheinland in early March this year. The Class 4 hail test uses solid ice balls frozen at -17°C with a diameter of two inches (50.8mm)to strike different locations of the glass surface of a PV module that include center, one corner and one edge along the metal frame, as well as some random places, at various impact velocities with the maximum reaching 76 meters a second (274 kilometers per hour). The kinetic impact energy of this Class 4 hail test carried out by RETC this time on JA’s PV modules is more than eight times higher compared to the energy registered in the previous hail test conducted by TUV Rheinland Lab in March when 45-mm hailstones with a striking speed of 30.7m/sec were used. Mr. Wei Shan , chief technology officer of JA Solar, commented, “In order for our products to withstand harsher weather conditions, it is a necessity that our modules pass the hail impact test under more stringent conditions. Passing the Class 4 Hail Test at RETC is a testament that further demonstrates the high quality and reliability of JA Solar's PV modules, as well as our tirelessly devoted efforts to meet the needs of our customers through continuous performance improvement, product innovation, and vigorous quality control.”


Comparison of PWM snd SVM based active filters

Abstract ~ The aim of this project is to simulate VSI and CSI based active power filters to Non-linear load for improving power quality. THD is used as measuring index for comparing performances of these filters. These filters can reduce harmonic in supply current. View here
Utility requirements document for small modular reactors
The Utility Requirements Document is a declaration of owner/operator requirements for new nuclear plants, large or small. More than 1200 specific changes were made in the revision to accommodate SMR designs, ranging from emergency planning and human factors design to detailed technical modifications associated with safety systems and building arrangement. Notably, the EPRI Utility Requirements Document can be used throughout a nuclear power plant project’s lifetime ~ before, during, and after technology selection ~ to support successful project execution.

Exelon's 120MW Perryman 6 natural gas power generating unit began commercial operation on Sunday, (June 28). Located at the company’s Perryman Generating Station near Aberdeen Proving Ground in Maryland, Perryman 6 increases the station’s full generating capacity to 475MW. The Pratt & Whitney Power Systems design FT4000 Swiftpac power generation unit consists of two simple cycle, aero-derivative combustion turbines. Perryman 6 is a peaking unit. It will run mainly on natural gas but will also have the ability to run on oil as a back-up.

Hazelwood fire costs $40m
On: 21-06-2015 Topic: General

Victoria’s (Australia) Hazelwood coal mine fire has cost the mine’s French and Japanese owners almost $40m to date, financial accounts reveal.

French energy giant Engie ~ formally GDF Suez ~ and Japanese trading house Mitsui & Co have also lodged an initial $30mn insurance claim to cover costs linked to the disaster and say the bill will continue to rise.

The multinationals own the Hazelwood mine and coal-fired power station in the Latrobe Valley that they operate locally as International Power Australia.

International Power had received $19.2m from its insurers at the end of December, according to a full-year report lodged with the Australian Securities and Investments Commission.

The accounts were lodged in April at the same time as the State Government moved to reopen the Hazelwood mine fire inquiry.

The inquiry will examine whether smoke from the blaze ~ which begun in February last year and burned for 45 days ~ caused premature deaths in the area.

International Power notes “the partnership may be subject to additional obligations as a consequence of the reopened public inquiry”.

The company says it had forked out $13.5m in capital expenditure at the site as of December as a consequence of the fire. It also absorbed $23.5m in costs related to dealing with the event.

Spokesman Trevor Rowe said the company would continue to absorb fire-related costs over the next two years.

Firefighting authorities spent about $32m to bring the blaze under control ~ a bill that some have suggested should be picked up by GDF Suez and Mitsui.

International Power took a $100m hit to its earnings in the wake of the fire and amid ongoing weakness in electricity demand as consumers increasingly switch to renewables.

Profit plunged by 70% to $42.3m in the year to December, down from $143.6m in 2013.

The joint venture also secured a two-year, $475m loan from ANZ and a number of Japanese banks to refinance the Hazelwood station’s debt load in June last year.

Mitsui & Co took a 28% stake in International Power in late 2013 for €301m ($442m).

International Power also owns wind farms and gas-fired power stations in South Australia as well as Melbourne-based energy retailer Simply Energy. — By John Dagge Herald Sun

ABB has won a fresh order from the Dubai Electricity and Water Authority for the 200MW Mohammed bin Rashid Al Maktoum solar park. Mohammed bin Rashid Al Maktoum Solar ParkDubai Electricity and Water Authority (DEWA) has placed an order with ABB worth $20m to expand the substation at the 200MW solar power park. DEWA is in the process of expanding the installed capacity of the project from 100MW to 200MW. In 2014, ABB was awarded a tender to set up sub-station for 100MW solar power capacity in the project. DEWA had, earlier this year, awarded the tender to implement 200MW (260MWp) solar photovoltaic power capacity at a record-low tariff of ¢5.98 per kWh. ABB will supply several key components to the project including three bays of 400 kilovolt and 11 bays of compact 132kV gas-insulated switchgear (GIS), power transformers, and IEC 61850-based open architecture automation and controls. The project is scheduled to be completed in 2016.

Investment in renewables in Asean grew by 83% between 2002 and 2012, according to the latest “Economic Insight” report by the Institute of Chartered Accountants in England and Wales. The report said renewable resources now accounted for just under half of the region’s entire electricity generation. However, Asean economies have not, in general, seen rises in the proportions of electricity generated through renewables. Singapore and Malaysia have seen rises of just 0.1% point each. The Sustainable Energy Association of Singapore estimates that the island nation could produce 10% of its energy from renewable sources by 2020, but to do so, it must ensure renewable capacity is added more rapidly than fossil-fuel generation. Meanwhile, nations in the Organisation of Economic Cooperation and Development (OECD) have been rapidly growing their own shares. Progress in the United States appears slow but in fact has accelerated considerably since 2008, when the new administration discontinued the previous sceptical stance on climate change. Europe’s progress is more representative of OECD trends, exhibiting an increase of 9 percentage points in the renewable share of electricity generation between 2002 and 2012.

GE is preparing to complete the delivery of an electrical conversion system for the Paimpol- Bréhat tidal project of the coast of Brittany, France. GE Power Conversion has been chosen to provide the complete system, both subsea and onshore for the array, developed by EDF. The array is set for operation by the end of 2015. GE Power Conversion is working with EDF to finalise the electrical conversion system by summer 2015. Relevant testing is currently taking place, prior to the installation of the system. Two OpenHydro 16-metre turbines will be connected to a common subsea converter that will transform the current to HVDC to provide 1MW of electricity.
