Siemens has begun shipping drives to Abengoa's Solana CSP plant after a multi-million contract was signed between both companies.

Siemens will provide 18 of its Robicon Perfect Harmony medium voltage drives, including ten, 4,000 hp GenIIIe drives, two, 2,000 hp GenIIIe drives and six, 800 hp GenIV drives.

Solana, the plant being built by Abengoa in Phenix, Arizona, is a 280 MW parabolic trough plant that is expected to be completed by 2013

“Siemens Drive Technologies division partners with customers like Abengoa to supply some of the most integrated drive train components in the U.S. Our motors, variable frequency drives and gearboxes provide tens of millions of dollars in energy savings annually, and deliver a strong return on investment by helping to boost net operating income. We are proud that Abengoa selected Siemens to be its partner for the Solana project, and look forward to the success of the solar plant,” says Doug Keith, president, Drive Technologies Division, Siemens Industry, Inc.

About Siemens drives

Siemens Robicon Perfect Harmony Drives, manufactured in New Kensington, Pa., are well suited to the power generation industry because they can ride through voltage dips, have a small footprint and requires no output transformer, harmonic line filters or power factor compensation.

These variable frequency drives (VFD) are unique, as each uses a series of low-voltage cells linked together and scaled precisely for a wide range of voltage and output power. The cell bypass ensures automatic bypass of a failed power cell in less than 500 milliseconds and instead of shutting down the entire drive, a process-tolerant protection system (ProToPS) provides a hierarchical system of warnings. This control strategy allows time to evaluate the situation and respond appropriately. This concept also enables easy access to drive components for scheduled maintenance.
