1. Introduction of YT SVG
YT Static Var Generator (referred to as SVG), is based on the principle of voltage-type inverter, using insulated gate bipolar transistor (IGBT) to control the magnitude and phase of the inverter AC voltage, thereby To achieve the purpose of reactive power and harmonic compensation. Due to the high switching frequency of IGBTs (up to 25.6 kHz), SVG can quickly compensate reactive loads and achieve very high compensation accuracy.
SVG is currently the best solution in the field of reactive power control. Compared with the traditional SVC represented by TSC, Static Var Generator has faster adjustment speed (response time no more than 5ms), high compensation accuracy (power factor after compensation reaches more than 0.99), and more flexible compensation method (both inductive reactive power and Capacitive reactive power can be compensated), and after taking measures such as PWM technology, the content of harmonics in the compensation current can be greatly reduced.
2. The Features of YT SVG
(1) Reactive power compensation algorithm based on adaptive linear neuron network (ADALINE), can learn parameters by itself, and be no need to set any control parameters, easy to debug.
(2) Two sets of external CT interfaces can flexibly configure application schemes and be convenient for on-site installation and wiring applications.
(3) Low power consumption and low noise. Using PWM speed-adjusting fan, the fan speed is adjusted with the output.
(4) Using the high-temperature and long-life electrolytic capacitors to ensure product life of up to ten years in rated environment.
The closed forced air duct design isolates the area that needs ventilation and heat dissipation from other areas. The components that are afraid of dust are isolated from the air duct to ensure that the temperature of the equipment is at a relatively low level during the operation of the equipment, which indirectly improves the life of the system. and will be afraid of dust.
(5) 24-hour full load aging ensures that the equipment is fully tested and tested before leaving the factory.
(6) The PCB three-proof paint process meets the use of humidity, dust, and other harsh environments.
(7) Equipped with capacitor switching control interface.
(8) The compensation method is flexible, which can compensate reactive power, harmonics and unbalance at the same time.
(9) Support multi-machine parallel connection, up to 10 units can be connected in parallel.
(10) Support mobile App and GPRS monitoring.
(11) Modular design, convenient for installation, operation and maintenance.
(12) The response time is less than 5ms.
(13) Rated voltage AC200V~480V.
3. The Application of YT SVG
YT Static var generator SVG is mainly used for compensating reactive power, improving power factor and optimizing power quality.
(1) Special compensation for large loads.
(2) Large industrial users.
(3) Substations of the power system.
(4) Comprehensive compensation of harmonics, reactive power and 3 phase imbalance.
