Upgrade for DCS at Maanshan Nuclear
Power Station
The upgrade will include new systems and simulator re-build services to update balance-of-plant control applications, and support operator training for Maanshan NPS Units 1 and 2
Invensys Process Systems has announced that Taiwan Power Company (Taipower) will implement I/A Series distributed control systems (DCS) from Foxboro for balance-of-plant control system upgrades for both units of the Maanshan Nuclear Power station located at PingTung County on the southern tip of Taiwan As part of the contract, Invensys Taiwan, a qualified Taipower supplier, will provide a range of professional services to assist Taipower with the controls modernisation project

The I/A Series systems will replace obsolete analogue systems installed when the plant was built, modernising the control schemes and overcoming increased maintenance and spare parts problems.
Based on a high-speed Ethernet system backbone, the I/A Series system will control the condensate, make-up water, feedwater heater, steam reheat, cooling tower and other balance-of-plant processes at the Maanshan facility.
Further, Invensys Taiwan will re-engineer the existing training simulation systems for the Maanshan station.
Maanshan Units 1 and 2 are pressurised water reactors, each with a net capacity of 963 megawatts.
In addition to implementing I/A Series process automation, Invensys Taiwan will work closely with the Institute of Nuclear Energy Research, a Taiwan government-owned organisation, to provide nuclear QA certification and re-licensing for Maanshan.
Invensys Taiwan will also work with the Taipower engineering, technical and operating personnel by providing a variety of services, including project management, engineering services, start-up assistance and training programmes.
The recent Invensys balance-of-plant controls contract with Taipower follows other Invensys projects for Taipower.
Previously, Invensys won a significant order for upgraded I/A Series digital controls in the Maanshan nuclear steam supply systems, which included feedwater control and associated control for the primary and secondary steam processes for each unit.
These projects were completed in 2003.
That same year Invensys Taiwan provided seismic switch controls for the safety system at Maanshan, and for the safety systems at two other Taipower nuclear generating stations, Chinshan and Kuo-Sheng.
These projects were followed by a digital upgrade for the feedwater control system at the Kuo-Sheng station.
