The official website of Shanghai Songjiang  will introduce to you: [Guangdong Province Zhaoqing Converter Station Project] bellows expansion contract information, Songjiang Group provides high-quality rubber joints for many converter station projects in Guangdong Province, the following is a detailed introduction about that  installation of bellows expansion in the converter station project effectively reduces pipeline noise.

The scanned copy of the contract of Zhaoqing Converter Station Project in Guangdong Province is as follows:

Zhaoqing Converter Station is the receiving-end inverter station of the ±500kV Guiguang primary DC transmission system. Zhaoqing Converter Station has been operating stably since it was completed and put into operation, and has maintained a high-load power transmission level. As of December 2017, a total of 175.82 billion kWh of electricity has been transferred. A converter station refers to a station established in a high-voltage direct current transmission system to complete the conversion of alternating current to direct current or direct current to alternating current, and to meet the requirements of the power system for safety, stability and power quality.

The main equipment or facilities that should be included in the converter station are: converter valve, converter transformer, smoothing reactor, AC switchgear, AC filter and AC reactive power compensation device, DC switchgear, DC filter, control and Protective devices, off-station grounding electrodes, and telecommunication systems, etc. The control regulation and protection system of the converter station realizes the following functions: stop and send DC power, control the direction of the power flow, adjust the quantity of the power flow and other electrical parameters, deal with and limit the abnormal operation of the converter valve and the interference caused by the AC and DC systems The impact caused, the protection of the equipment of the converter station, and the monitoring of various parameters of the converter station. The operating performance and safety and reliability of the converter station and DC transmission system are closely related to the performance and reliability of the control and regulation system, and have an important impact on the operation of the entire power system. Therefore, the control, regulation and protection system of the converter station is the intelligent part of the converter station, and its development trend is to adopt microcomputer technology.
