SINAMICS PERFECT HARMONY GH150
Increased flexibility with different cooling types and extended power range
Now even more possibilities while staying on the safe side: The SINAMICS PERFECT HARMONY GH150 is the optimum drive for applications in the medium voltage range 4 - 13.8 kV, such as compressors for within the oil & gas industry. With its four different cooling types it offers maximum flexibility while at the same time offer highest availability due to its cell-based design. The ability to bypass any cell during operation in average less than 1 ms, and maintain the full output voltage, is why this drive offers the utmost availability. Being a member of the million-times market-tested SINAMICS drives family the SINAMICS PERFECT HARMONY GH150 provides almost sinusoidal voltage output and is equipped with the latest version of SIDRIVE IQ components to allow access to remote onsite data and provide live-data of the drive.
Benefits at a glance
The transformer can be chosen according to specific requirements. In most cases the transformer is placed in an outdoor transformer bay, thus eliminating the need for active cooling and E-House space for the transformer, also reducing the fire load within the building. In most cases oil cooled (ONAN/KNAN) transformers are used. However, the transformer can also be placed indoor if required (e.g. for offshore applications). The use of dry type transformers is also possible
The control unit can be placed up to 50m away from the power section of the drive and can thus be placed in a different room which does not contain any Medium Voltage equipment. This will allow access to the control unit also to operators that are not certified for working with medium voltage, thus allowing the customer to use his personnel more flexible.
Any voltage-source inverter (VSI) is equipped with the DC-Link capacitors as a temporary energy storage. With M2C topology the capacitors are distributed within the power cells and not concentrated as one large capacitor, as in 3-level or 5-level VSI drives. Thus the fault energy is distributed and much lower for every individual capacitor. In case of a failure that affects a capacitor the effects are very local and far easier to fix
