title = "An Improved Precharging Strategy for Soft Startup Process of the Cascaded H-Bridge STATCOM",
abstract = "The cascaded H-bridge (CHB) Static Synchronous Compensator (STATCOM) is widely used for reactive power compensation in medium- and high-voltage applications. Precharging is a critical step in its operation. However, traditional precharging methods are difficult to charge the DC capacitor voltage to the nominal operating level, resulting in inrush current during startup. Based on the strategy of bypassing submodule (SM) capacitors, this paper presents an improved method to precharge the DC capacitor voltage to the nominal operating voltage and introduces a transitional step to reduce the inrush current caused by the bypass operation. The proposed method eliminates the risk of overheating charging current limiting resistors and enables reliable startup from a hot standby state.",
