The Siemens Drive Technologies Division has increased the upper power limit of its Sinamics G150 series of converters from 1500 to 2700 kW. These low-voltage converters are designed for applications without regenerative feedback, for example those that involve moving, pumping or compressing substances. Due to the variable speed drive operation with frequency converters, energy is saved, in some cases by up 70%.
The cabinet units can be connected to 2-winding transformers. In order to minimise low frequency harmonic effects, 12-pulse operation on a 3-winding transformer is also available as a standard feature. The use of IGBT power semiconductors and a special cooling concept ensure that the converters are quiet and compact in all available degrees of protection from IP20 to IP54. Units are easy to commission and operate thanks to the AOP 30 advanced operator panel and the Starter PC tool. The rugged and simple design ensures easy maintenance with user configurable options to suit most applications.
Measuring and analysing PV circuit performance Comtest
Electrical Power & Protection
Regardless of the test method, you must know the plane of array irradiance and cell temperature to evaluate PV circuit performance. Proper sensor types and test methods like the Fluke Solmetric PVA 15i-V curve tracer should be used for reliable results.
