HYSVG Static Var Generator

Short Description:

Fundamental

The basic principle of STATCOM, a static var generator (also known as SVG), is to connect the self-commutated bridge circuit directly in parallel with the power grid through the reactor, and properly adjust the phase and amplitude of the output voltage of the AC side of the bridge circuit or directly control Its AC side current can make the circuit send out reactive current that meets the requirements, and realize the purpose of dynamic reactive power compensation.

Applications

1. Hoists, rolling mills and other heavy industrial occasions Hoists and rolling mills are typical impact loads, which mainly exist in various mining production occasions and metallurgical industries, and have the following impacts on the power grid:
●The impact of reactive power is large, causing voltage fluctuations in the power grid, and in severe cases, it interferes with the operation of other equipment and reduces production efficiency;
●The power factor is low, and a large amount of reactive fines need to be paid every month;
●Some devices generate harmonics, which endanger the safety of the power grid.
2. Drilling Power Supply System The main loads of the oil and gas drilling and platform power supply system include drawworks, rotary table, mud pump, etc. Due to the particularity of drilling conditions, this system is a typical impact load. The impact on the grid is as follows:
●Large reactive power impact and low power factor;
●Large current harmonics;
●Serious voltage fluctuation and high voltage distortion rate affect the power supply of control system, PLC, mud logging equipment and other equipment.
