Smart Three-phase Unbalance Regulator (STUR) is a new type electronic device which is used to manage three-phase unbalance and compensate reactive power. The device adapts the advanced control algorithm to separate the plus or positive sequence and negative sequence component of unbalanced current and reactive power. Through triggering power device IGBT, the inverter could make the offset contrast current, which can eliminate imbalance, and compensate reactive power.
More Functions and More Modes
This device is multi-functional. It has the functions of zero sequence compensation, negative sequence compensation, reactive power compensation and harmonic compensation
Specific harmonic compensation function, zero sequence and negative sequence and reactive compensation function
Friendly UI; 7 inches HD color touch screen. The screen can display the parameters of system and device in real time.
WIFI, 3G/4G communication mode, various APPs can be installed, which can enable monitoring and operating in time
Advanced Control Strategy and Topological Structure Design
This device based on IRPT detecting technologies, the harmonic current can be monitored in time and the change of loading harmonic can be traced, which make this device highly controllable and reactive.
The LCL topological structure of filter is adapted, when outputting harmonic current, the high frequency IGBT switching harmonic interference will not be introduced. And it is suitable in any field with grid system impedance and no resonance will happen.
