Range expansion of our turbo compressor engines
The VEM Group always focuses on meeting customer requirements. This is accompanied by the constant further development of engines with ever higher performance. This also applies to an order that the Sachsenwerk in Dresden received in June 2019, which means that the existing product portfolio has been and is being further expanded.
Technical data and application of the motor
Specifically, a compressor engine was built with:
- a power of 40 MW,
- a voltage of 11 kV and
- ordered at a speed of 1,500 rpm.
The electric motor is a drive for a turbo compressor for compressing process gases in the petrochemical industry. The compressed gas is then broken down into its components or fed into a chemical process and further processed.
The motor is designed as a synchronous salient pole machine with screwed-on solid pole roofs. The start takes place with the help of a multilevel voltage link converter, which, with its almost sinusoidal output voltage, does not cause any additional insulation stress and only causes low losses. After ramping up to nominal speed Unenn and synchronization, the system switches to mains operation at 11 kV.
The gradual expansion of the VEM portfolio
In the past, VEM's portfolio of turbo compressor drives was mainly limited to an output of up to 20 MW. However, several projects have shown that the skills for producing electric motors with higher performance already exist at the Sachsenwerk. For example, five air-cooled, 4-pole motors with an output of 25 MW were delivered in Ex version, another was commissioned by the same customer and is currently being manufactured.
VEM was also able to overcome all the challenges of the current project, which was proven in test runs in the test field. The engine was therefore delivered to the customer in July 2020. Two more will follow, one of which is already being manufactured and delivered in the third quarter of 2021. The functionality and structure of the engines are similar.
A turbo compressor drive with an output of 55 MW is currently being manufactured, in which the knowledge from previous projects is used effectively. We look forward to further exciting projects and are happy to realize projects with engines of up to 80 MW for our customers.
