Siemens supplies drive

Siemens supplies drive and power equipment for a pulp and board project Stora Enso in Guangxi, P.R.China, one of the biggest pulp and board producers, have built new integrated production plants. With the implementation of this major project Siemens was on board. The project covered the drive technology, automation of the entire factory, the complete power engineering systems, and the power generation. CONTROL AND DRIVE TECHNOLOGY Stora Enso is domiciled in Helsinki , and is one of the world’s largest forest industry companies. It awarded Siemens a major order in connection with the construction of a new plant in China. The order covered the drive technology, automation of the entire factory, the complete power engineering systems, and the power generation. The new, integrated production plants for pulp and packaging board were built in the Chinese province of Guangxi, and the board machine went into operation in the first quarter of 2016. Siemens delivered an Integrated Drive System with over 160 drives for the packaging board machine, and also supplied the process control system for the plant-wide automation. The order also included a steam turbine to generate the power, and the power distribution for the entire factory. Siemens supported Stora Enso with the implementation of this major project. The company placed great value on having an internationally experienced supplier in China that could supply everything from a single source. Siemens was consequently also responsible for handling the entire engineering of the drive and power solutions, the detailed planning, as well as for supervising the installation and commissioning of the electrical systems. Over 160 matched motors and frequency converters installed An integrated drive system from Siemens with over 160 drives was installed in the packaging board machine. It is over 300 meters long, and produces 450,000 metric tons of board per annum, which are used to produce beverage packaging, among others. Harmonized Simotics low and medium voltage motors, and Sinamics frequency converters achieve high efficiency and availability. The optimized components and the well-matched drive train enables Stora Enso to benefit from a reliable, productive machine. Efficient generation by a 59 megawatt steam turbine The power is generated by an SST-800 industrial steam turbine from Siemens with center admission and an output of 59 MW. Siemens is also responsible for all the high, medium and low-voltage switchgear, line, power and distribution transformers, as well as the emergency power supply, power monitoring and control system. About Siemens Siemens is a global powerhouse focusing on the areas of electrification, automation and digitalization. One of the world’s largest producers of energy-efficient, resource-saving technologies, Siemens is a leading supplier of systems for power generation and transmission as well as medical diagnosis. In infrastructure and industry solutions the company plays a pioneering role. As of September 30, 2015, we had around 348,000 employees in more than 200 countries.

Siemens supplied a Distributed Control System Sipaper DCS, the latest generation 8.1 of the PCS7 process control system, that enables the entire plant to be automated. Siemens also equiped all the drive systems, the energy switching and monitoring (ESM), and the steam turbine with the same PCS7 automation system. This gives Stora Enso all the advantages of a fully standardized, factory-wide automation system.
