Patnow II– maximum availability from minimum fuel input Control Systems Reference Instrumentation, Controls & Electrical SPPA-T3000 Control System allows the Patnow II power plant to operate fully automatically – an I&C system which maximizes plant availability and optimizes the use of fuels. The Result ■ Maximum plant availability thanks to automated procedures and integration of all technological components ■ Increased economic efficiency thanks to the optimized use of fuel and extended durability The Plant Constructed in 2008, the Patnow II steam power plant is the most recent of the four power plants operated by ZE PAK SA. Patnow II comprises one unit with an output of 474 MW. Located in Konin, 100 km to the east of Poznan, it supplies the region’s end users with electricity. ZE PAK SA provides a total of 8.5 % of Poland’s energy requirements and is thus the second largest producer of electricity from lignite in the country. The Task When the plant was constructed, it was important to create an overall concept which would allow the unit to be operated fully automatically, including the associated ancillary facilities and flue gas cleaning plant, but also to incorporate external systems manufactured by other suppliers. Moreover the control system should enable the plant to be operated economically with a long durability and guarantee maximum availability for all load scenarios. Our Solution SPPA-T3000 ensures a high level of automation which increases plant availability and economic efficiency. By implementing this I&C system all operations of the unit including associated auxiliary and auxiliary system were fully automated. Additionally the existing systems and technological components manufactured by other suppliers were incorporated. This modern I&C system monitors the use of fuel, assesses the necessary input and optimizes its usage. Thereby the economic efficiency of the plant is increased. The automated start-up and shutdown processes likewise fulfill the specified load operation requirements according to the statutory regulations which apply in Poland. Also the power plant’s durability is increased by remaining within the load limits for cold and warm starts and during load cycling. The operator control and monitoring system for decentralized process control and archiving is easy to use. It also enables power plant staff to quickly filter out data which is relevant to them and to make changes to processes without any errors. “When building our latest power plant, Patnow II, we wanted to make sure that the unit would operate on a fully automatic basis by using state-of-the-art technology. Thanks to the SPPA-T3000 control system, we now have a power plant that offers maximum availability from a minimized resource input.” A. Grudzien, Power Plant Manager Patnow II Answers for energy.
