Dual Loop Control Variable Frequency Drive Controller Speed Control For Steel Plant

Dual Loop Control Variable Frequency Drive Controller 3 Phase Speed Control For Steel Plant

Three Phase 10KV 1200KW Medium Voltage Electric Motor Speed Control For Steel Plant And Power Station, with high speed DSP as the control core, uses space voltage vector control technology, power unit series multilevel technology, with high reliability, easy operation and high performance as the design target, meets the user's various load speed control energy saving, improves the production process needs, is a high to high voltage source type frequency converter. Its harmonic finger is less than IEE 519-1992 harmonics national standard, high input power factor, good output waveform quality, no need to use input harmonic filter, power factor compensation device and output filter; no harmonic induced motor additional heat and torque ripple, noise, output dv/dt, common mode electric voltage and other problems, can use common asynchronous (or synchronous) motor.
