Product Overview
ZG-dSVC HV dynamic SVC is developed by Zhiguang Electric's R&D team with Tsinghua University relying on its technologies and experience in high-power electric and electronic apparatuses, HV reactive power automatic compensation control, and power automation.
Such SVC has passed the type test performed by the national authority and has been successfully applied in metallurgical, coal, and wind power generation industries.
Principle & Construction of ZG-dSVC
According to the compensation theory, SVC is divided into the magnetically controlled reactor (MCR) and the thyristor controlled reactor (TCR). Such TCR-type SVC features fast speed control, low noise and loss. ZG-dSVC dynamic SVC adopts such TCR scheme.
Such ZG-dSVC consists of a full digital control system, a thyristor controlled reactor (TCR), a filter capacitor bank and a cooling system, as shown in Fig. 1.
Technical Performance & Features of ZG-dSVC
Major functions of ZG-dSVC:
1. Improve the electric power system stability and the grid transmission capacity;
2. Suppress voltage fluctuation and flicker, and improve the power quality;
3. Dynamically compensate reactive power and improve the power factor;
4. Filter harmonics and solve related issues; and
5. Reduce the loss of transformers and transmission lines, and save power.

Product Description: Type KD-XH quick arc suppression system for distribution networks consists of a grounding transformer, arc suppression coils, a control cabinet and a central data display. The arc suppression coils are complete with primary and secondary windings, with 100% short-circuit impedance. The primary winding is connected to the neutral point of the distribution network as operating winding, while the secondary winding is connected backwards to two silicon controlled rectifiers (SCR) in parallel as control winding. The conduction angle of such SCR controller ranges between 0 and 1...

With neutral grounding via an arc suppression coil, the transient single-phase earth faults can be accurately identified to quickly enter and exit the offset mode. For non-instantaneous single-phase earth faults, the grounded lines can be accurately determined according to the set time to eliminate failed lines and improve the power supply reliability of the grid.   Technology Overview: Our KD-XHTZ multi-tap arc suppression coil apparatus with automatic follow compensation contains the secondary paralleled damping resistor and perfect secondary protection technologies and is equ...

With the recent development of distribution systems and further renovation of urban and rural distribution networks, numerous cables have replaced previous overhead transmission lines. To a certain extent, the decrease in the probability of single-phase earth faults reduces the high trip-out rate arising from low-resistance grounding systems. However, the high line selection accuracy of such low-resistance grounding systems are accepted by the majority of users. Consequently, they still have a wide range of applications in some urban distribution networks. Product Description: Such neutra...
