Product Description
Product Overview
The hybrid SVR integrates SVR with power electronics, combining coarse regulation by the SVR with fine regulation by the power electronic module. The regulation accuracy of the SVR can be set as ±5%, while the regulation accuracy of the power electronic module is <1%, enabling more flexible and precise voltage control. This combined approach can also reduce the operating frequency of the on-load tap changer and improve the service life of the SVR. It is particularly suitable for applications with frequent voltage fluctuations and conditions that exceed the voltage limit.
Structure and Working Principle
The hybrid SVR consists of the SVR autotransformer voltage regulator, a power electronic module, and a series coupling transformer. The SVR autotransformer voltage regulator performs bidirectional coarse voltage regulation, handling adjustments that do not require frequent switching. The power electronic module features a series-shunt configuration and combines with the series coupling transformer to achieve bidirectional fine voltage regulation.
Fine voltage regulation is realized on the series side of the power electronic module. By adjusting the series-side of the power electronic module. By adjusting the series-side inverter, the voltage across both ends of the series coupling transformer is changed to enable bidirectional voltage regulation and voltage imbalance compensation.
Main parameters
Note: 1. The selected voltage class shall match the voltage class of the line;
2. The rated capacity is typically 1.1 to 1.2 times to the total capacity of the downstream distribution transformers at the regulator's installation point.
Features
