Power for PKN Orlen chemical plant

2013-08-05 - ABB is providing the electrical systems and grid connections for a 460 MW combined cycle power plant in Wloclawek, Poland for PKN Orlen, one of central Europe’s largest crude oil refiners and fuel retailers. A GE-SNC Lavalin consortium is building the plant, which will provide reliable and efficient power to a chemical facility operated by Anwil, a PKN Orlen subsidiary.

ABB provided full technical support to the customer, GE-SNC Lavalin, from the start of this project. The power plant concept will be single shaft and consist of a gas turbine, a heat recovery steam generator (HRSG), and a steam turbine complemented by related electrical and mechanical balance of plant. The power generated will be used by the chemical plant's 110 kV grid and the 220 kV national grid.

ABB will supply a customized solution that connects the plant to bothgrids, internal and external. The interconnection of the 110 kV and the 220 kV grid consists of two step-up transformers in combination with a phase shifting transformer and the related high voltage switchgear bays.

ABB's early work with GE-SNC Lavalin on this project and the customer's belief in the ABB team's execution capabilities were instrumental in winning the order. ABB's solution enables a very flexible power flow to the 110 kV and the 220 kV grid, and provides PKN Orlen with optimized, economical power generation for its production plant while enhancing the security of the energy supply.

The future power plant was modeled using the ABB electrical system analysis tool NEPLAN®, which enables ABB to analyze, plan, optimize and simulate electrical networks with a very high degree of accuracy, for steady state as well as dynamic calculations.

The phase shifting transformer makes control of the active power flow possible. It will compensate for the phase angle shift as a consequence of the different impedances. This economical solution to active power control provided SNC Lavalin with a unique selling point and was a key factor in the project's success.



In addition to the transformer package, ABB's scope of supply also includes the complete electrical balance of plant, the generator circuit breakers, isolated phase bus ducts, medium voltage and low voltage switchgear, emergency power supply and cable systems.

A project management team from ABB Poland and ABB Germany is responsible for the execution of the project. ABB Poland brings deep knowledge of local requirements in support of the design team from Mannheim, Germany, and is responsible for all site activities.

ABB combines robust project execution capabilities in large and complex projects with careful attention to fulfilling local requirements. This core expertise and ABB's best-in-class technology provide major advantages for customers, compared to our competitors.

ABB's installed base of power and automation products and systems in the power and water industries has become one of the largest in the industry, due to factors like integrated solutions and engineering expertise, global footprint and resources and project execution professionalism.

During the signing ceremony of the 30 million Euro ABB project, the SNC Lavalin Polska representative thanked ABB for its excellent technical contribution to the project's success.
