Static var generator capable of effectively improving transient stability of power grid voltage

Abstract

The invention relates to the technical field of application of static var generators, and discloses a static var generator capable of effectively improving the transient stability of power grid voltage. The static var generator comprises a var generator main body, wherein a control panel is fixedly arranged on the front surface of the var generator main body. According to the invention, a heat dissipation box is fixedly arranged on the back surface of the var generator main body, a motor, a rotating shaft and a fan are fixedly mounted in the heat dissipation box, when the motor operates, the rotating shaft and the fan are driven to rotate to generate wind energy, wind energy enters the var generator main body through a ventilation net to effectively cool the interior of the var generator main body, a ventilation opening corresponds to the ventilation net to form a ventilation channel, and the wind energy with high temperature is exhausted from the ventilation opening, so that the var generator main body is ensured to operate at normal temperature, and the purpose of effectively improving the transient stability of the voltage of the power grid is achieved.

Description

technical field [0001] The invention relates to the technical field of application of static var generators, in particular to a static var generator that can effectively improve the transient stability of grid voltage. Background technique [0002] The static var generator is to connect the self-commutated bridge circuit to the power grid through a reactor or directly in parallel to adjust the phase and amplitude of the output voltage of the AC side of the bridge circuit, or directly control the current on the AC side of the bridge circuit, so that the circuit absorbs or Send out reactive power that meets the requirements to achieve the purpose of dynamic reactive power compensation. Wherever low-voltage transformers are installed and next to large-scale electrical equipment, reactive power compensation devices should be equipped (this is the regulation of the national power department), especially those with power factors Lower industrial and mining, enterprises and residen...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a static var generator that can effectively improve the transient stability of the grid voltage, which has the advantages of effectively improving the transient stability of the grid voltage, and solves the problem of heat dissipation without a perfect system. When the static var generator is running at high speed, the high temperature generated cannot be reduced quickly, resulting in too high internal temperature of the equipment, running stuck or even mechanical failure, which affects the problem of improving the stability of the grid voltage transient
