Monitoring planet earth with ABB instrumentation

Friday, March 13th, 2009

Advanced ABB instrumentation is helping space and meteorological agencies all over the world better understand complex processes in the atmosphere and improve their ability to forecast the weather and monitor global climate change. The latest is the Japanese satellite GOSAT (Greenhouse gases Observing SATellite), launched Jan. 22. Its main component is an ABB spatial interferometer.

ABB is the world’s leading supplier of advanced analytical solutions to measure gases and chemicals in the earth’s atmosphere and monitor the dynamic processes that create the world’s weather and the forces that create our climate.

Many of the world’s space agencies and meteorological offices rely on ABB analytical solutions to take these vital measurements in ground-based, airborne and space applications.

Often orbiting in satellites hundreds of kilometers above earth, the solutions provide unique, accurate data on critical phenomena such as ozone depletion and greenhouse gas concentrations, as well as the presence of toxic chemicals during and after natural and manmade disasters.

The cutting-edge ABB solutions are based on Fourier transform infrared spectroscopy (FTIR) and are the main analytical components on the satellites and aircraft that carry them. Among the many high-profile installations are: (more…)

All in days of work

Sometime, the GPRS coverage & priority issue is a turning down subject in our AVLS operations. Despite of GPS data errors and interferences, we choose to add SMS  mode for failsafe function to our AVLS architecture. It’s not really a big deal to develope the back engine, but in considering the alarm dispacthing functions. Maybe, it will become another turning down factor in our bussiness. the dispatcher should be really intelligent to determine the raw data despite of many of uncertainty factors that always bother. We bought a quad-core dell 1U rack server in order to replace our old beloved application server, a 4 pentium 4 Dell 5U tower server. We done doing upgrades to database server, and now working on the back-end & front-end application test. In another hand, we are migrating the Telemery System for waterworks…. developing a friendly GUI for Flood Monitoring System plus testing the alarm dispatching functions, still handling data loses in ABB EM meters integrations… sigh!

ABB innovation increases breaker performance in power plants

Friday, August 8th, 2008

An ABB innovation has increased the performance of generator circuit breakers by more than 25 percent while simultaneously reducing the footprint, weight, noise levels and maintenance requirements of these critical power plant components.

The innovation has enabled ABB to increase the nominal current of its HECS family of generator circuit breakers (GCBs) from 18,000 amps (A) to 23,000 A, an increase of almost 28 percent.

Previously GCBs of this rating required a so-called ‘forced’ cooling system of pumps, fans or motors to counteract heat dissipation and keep sensitive breaker components within their rated temperature tolerances.

About 70 percent of the world’s GCBs are engineered and manufactured by ABB, which is launching three new GCBs with heat pipe cooling in 2008

ABB has eliminated the need for these cooling devices by developing an innovative heat pipe cooling system that makes the HECS range lighter, slimmer and quieter than was previously possible.

In addition to offering a substantial increase in nominal current capability, the maintenance requirements of the new GCBs are – as with all HECS breakers – extremely low.

Nominal and short-circuit currents generate a tremendous amount of heat. The higher the nominal current, the more heat is generated. A cooling system – either natural or forced – is therefore required to keep the breaker within its temperature limit.

ABB’s HECS breakers are quieter, smaller and lighter thanks to an innovative approach based on a heat pipe cooling concept.

A forced cooling system is itself a generator of heat, which in turn limits the nominal current capability of the GCB to 18,000 A, as well as creating extra weight and a larger footprint.

Natural cooling has its own engineering challenges and only becomes feasible for nominal currents above 13,000 A by increasing the dimensions, weight and footprint of the breaker components.

The success of the ABB heat pipe solution is to solve the limitations of the two existing technologies. It requires no electricity to operate and is virtually maintenance-free and silent.

Generator circuit breakers are a critical component in power plants, protecting both the generator and the power transformer. ABB has the broadest GCB portfolio on the market, covering power ratings of more than 1500 MVA and nominal currents in excess of 50,000 A.

ABB takes underground mining to a new level

Sunday, July 6th, 2008

Underground mining relies on hoists to transport people, equipment and ore between the mining zone and the surface. ABB hoist systems are raising productivity, energy efficiency and grid stability for customers all over the world.

Mine hoist systems are a key component in underground mining. They are the most efficient means for transporting crushed ore to the surface from the mining area hundreds or even thousands of meters below ground. And, they are often the only way of conveying staff and equipment up and down the mine shafts.

Speed, reliability and safety are essential in this demanding round-the-clock process, as the efficiency of the hoist system determines the mine’s productivity and eventual profitability.

ABB’s showcase hoist systems include installations at an iron ore mine in Kiruna, Sweden, operated by LKAB, a state-owned mining company, and a potash mine in Saskatchewan, Canada, run by Mosaic, a maker of fertilizer.

The Kiruna mine is the world’s largest underground iron ore mine and its 11 ABB mine hoists make it the largest hoisting plant in the world. ABB is currently upgrading the four underground hoists and has supplied a seventh surface hoist to enable LKAB to boost production capacity by 25 percent to 33 million tons of crushed ore a year.

Mosaic’s Esterhazy mine is one of the largest potash mines in the world. ABB recently upgraded one of two production shafts to increase skip capacity by 50 percent and boost mine production by 1.1 million tons a year.

The 8.6-megawatt (MW) motor and drive solution – the most powerful hoist system in the world – has improved energy efficiency at the Esterhazy mine by an estimated 5-8 percent. Despite its huge size and power requirements, it maintains grid stability without the need for additional power correcting equipment. (more…)

ABB wireless motion detector with almost zero energy consumption

Sunday, July 6th, 2008

busch-watchdog.jpgABB has developed a top-of-the-range wireless motion detector that does not consume mains electricity and is powered – for a remarkable 5-7 years – by just three standard 1.5 volt alkaline batteries.

Launched to widespread industry acclaim in Germany in 2007, the new Busch-Watchdog wireless motion detector breaks new ground in energy-efficient and cost-effective building surveillance technology.

Powered by just three inexpensive AAA alkaline batteries (the sort commonly used in portable electronic devices like digital cameras, MP3-players and remote TV controls), the new motion detector uses an innovative design to eliminate the need for costly wiring and reduce power consumption to uniquely low levels.

Battery lifespan can be extended even more – to 10 years – by using lithium iron disulfide cells instead of standard alkaline batteries.

Industry benchmark

ABB developed the product in collaboration with Busch-Jaeger and MEMS Inc, a Swiss-based company founded by former ABB engineers. Busch-Jaeger is an ABB company and a world-leading brand in low voltage building installation products and solutions. Its range of Busch-Watchdog motion detectors is widely considered the benchmark in detection capability, reliability and esthetic appeal.

Equipped with an exceptionally powerful lens and broad range of functionality, the Busch-Watchdog detects any moving object within an unparalleled 16 meters of the detector. Unrestricted by power connections, the new wireless variant brings complete freedom of placement to users. It can be attached to a building, garage, perimeter wall, porch or ceiling.

The innovation is based on low power-consuming components and embedded system technologies in three interconnected modules compromising sensors, radio communications and microcontrollers.

The microcontroller supports several power-down modes that allow the detector to go into various states of ‘sleep’ during daylight, gradually waking up as the light fades. Full recovery is instantaneous (a few microseconds) if a moving object is detected.

Busch-Watchdog wireless motion detector is one of several wireless products in the Busch-Jaeger portfolio.
