Introduction to SVG Module Products
Compared with the passive devices represented by the traditional TSC, the new power static reactive power generator SVG has a faster adjustment speed and a wider operating range, and the use of PWM technology such as multiplexing has greatly reduced the content of carrier frequency harmonics in the compensation current. The new-power SVG module is smaller than the reactants and capacitor components used by the TSC, greatly reducing the volume of the compensation device. Each module of the new power SVG can work independently, and the modularization of the power unit makes the device capacity easy to expand and maintain.
Comparison of SVG Modules and Traditional Capacitor Electro-reactance Compensation
product
New Power SVG Module
Traditional capacitance reactance compensation
Reactive power compensation capacity
Gradless adjustment from capacity to rated sensibility, good compensation effect
Graded casting and cutting adjustment, there are cases of overpayment and underpayment, the compensation effect is poor
Compensatory capacity
Module nominal capacity is the rated output capacity of the device, the selection of simple
The actual output capacity of the module is less than the nominal capacity of the capacitor. It is necessary to use the formula to convert it. The selection type is relatively complex.
Full Response Time
Full response time is fast, ≤ 3ms
Full response time is longer, ≥ 30ms
Three-phase imbalance management
Three-phase AC through the DC side connection, can deploy work
Rate, three-phase unbalanced governance ability
No such function
reliability
Module units in parallel, backup each other, fault units are not shadow
Sound machine running, high reliability
Self-healing capacitor is easy to harmonic with the system after the tolerance attenuation
Vibration, damage to equipment in the system, poor reliability
Useful life
Adopt imported electric electronic components IGBT, no easy
Loss, design life greater than 20 years
The capacity value of self-healing capacitor decays rapidly during use, and the general service life is 2 to 4 years.
