1 Precautions for the operation and maintenance of filter and shunt capacitor devices 1.1 Monitoring of capacitor unbalanced current operation 🌟One of the most important functions of the AC filter and the shunt capacitor is to provide reactive power for the DC system. When the reactive power does not meet the absolute minimum filter (the absolute [...]

1. The Importance of Equipment Installation Tracking 💐The DC converter station usually shoulders the important task of interconnecting large-scale power grids and transmitting electric energy with high power. The safe and stable operation of a single station often determines the safe and stable operation of the large power grid system, and the safe and stable operation [...]

1. Composition and structure of filter and parallel capacitors device 🍏The AC filter consists of high and low voltage capacitor banks (capacitor towers), reactors, resistors, lightning arresters, current transformers (oil-filled, silicone rubber, photocurrent transformers) and other metal connectors, supports, protective parts, etc. composition. The AC filters often used in the design of DC converter stations include [...]

🍏The configuration of AC and DC capacitor filters in the converter station is mainly based on the harmonic components and reactive power requirements of the AC and DC sides of the converter station, and the configuration of the parallel capacitors is based on the reactive power requirements of the AC side of the converter station. During [...]

Let's go through this chapter to understand the role of the lower parallel capacitor device and the harm of harmonics. 🌈Usually DC transmission converter stations are divided into DC area and AC area. Compared with conventional AC substation equipment, there are essential differences between DC area equipment and conventional AC substation equipment. There is no essential [...]
