Usages/Functions & Pictures for Resistors in Field
Wind turbine pitch system, wind turbine electronic control system and converter, small and medium-sized wind turbines (including grid-connected/off-grid type): apply in wind power generation Inverter Low Voltage Ride Through (LVRT) technology for wind turbines. It is used on the rotor side of the wind turbine to bypass the rotor side converter. When a low voltage disturbance occurs in the grid, it prevents the DC bus grid, it prevents the DC bus voltage from being too high and the rotor current from being too high. Mainly works in fault condition, damping stator magnetic chain. The resistor can dissipate large amounts of energy in an instant.
★ Energy storage pre-charging role.
★ Inverter/driver braking,brake function.
★ Drain, slow Power-Up.
★ Neutral grounding load (transformer, resistor working time is mostly 10s-30s, few is 60s).
★ Loop protection function (inverter DC/AC).
★ Generator test load.
Resistors suitable for such application
★ Aluminum Housed Resistor Series
★ High Voltage Resistors Series
★ Wirewound Resistors Series (DR)
★ Cement Resistor Series
★ Load Bank
★ Stainless Steel Resistors
Requirements for Resistor
General use of aluminum cased resistors are continuously rotating, so resistor is required to be vibration-proof.
