An LCD testing line
A power electronic solution of five 1500 kVA PCS100 and three 3000 kVA UPS-Is (Industrial UPSs) has been provided by ABB. The entire order of PCS100 UPS-Is for this electronics giant equals over 16.5 MVA. They will be installed in China, in a leading South Korean electronics company. ABB have also supplied a large number of PCS100 AVCs (Active Voltage Conditioners) and UPS-Is (Industrial UPS) to other semiconductor and LCD plants. This cutting edge technology gives dependable critical asset protection, to ensure voltage swells and sags are eliminated.
The need for a continuous and clean electricity supply increases as industrial plants become more advanced. Flat panel LCD manufacturing and modern semiconductor plants cost billions of dollars to build, and are inclined to voltage events like short outages and sags which can cost many millions of dollars in lost production each time.
ABB have broadened their effective PCS100 range of industrial grade UPS units to 3 MW and will provide three units of this rating and five of 1.5 MVA for a huge new LCD facility.
The UPS-I is part of ABB’s successful PCS100 family of power protection products which also includes the AVC (Active Voltage Conditioner) and STATCOM-I (Active Current Conditioner). The UPS-I can employ a variety of storage technologies but in this instance, instead of traditional lead acid batteries, super-capacitors have been chosen for back-up, because of their very high reliability and 15 year life.
UPS back-up times of seconds, rather than the minutes more typical for commercial UPSs, have been selected because longer term outages are an immensely rare occurrence for these transmission-connected customers.
Built around modular redundant inverter technology with a centralized industrially rated static bypass switch and additional electromechanical fail safe bypass, the UPS-I is exceptionally serviceable and reliable. ABB’s Napier New Zealand-based factory has tested and passed the 3 MW rated units to be provided to the Chinese LCD facility.
Cheaper cost of ownership is also a massive advantage of the single conversion UPS-I topology with better than 99 percent efficiency. This means exceptional energy savings when compared to other alternative power protection technologies. The heavily rated thyristors in the bypass circuit also mean that the fault levels, overloads, and current distortion typically observed in industrial applications can be handled easily.
