Application background
HVDC technology is now the world's most advanced and most energy-efficient power transmission technology and is also one of China's focuses on development of technical equipment areas.
Direct current transmission has no stable problem of synchronous operation between two AC systems; It has advantages such as rapid control system respond, accurate adjustment, easy to operate; Line voltage distribution evenly and small running loss, line investment and running costs of DC transmission all less than AC transmission systems, so DC power transmission system has become an important part of electricity construction and also major technical area of main technical equipment localization. "Eleventh Five-Year Plan" has been clearly pointed out: "the equipment manufacturing industry will rely on key construction projects and adhere to combination of independent innovation and technology introduction, strengthen policy support and improve the localization level of major technical equipment, particularly achieve a breakthrough in the efficient and clean power generation and transmission substation areas to improve overall level of R & D, core components, manufacturing and system integration.
Converter valve is a bridge arm required by three-phase converter to achieve inversion, and is also a basic equipment of converter that can achieve mutual conversion of AC and DC, and its safe operation play a central role in the whole HVDC transmission project. Safe and reliable closed-loop water cooling system is very important to precise indicators control such as cooling water temperature, flow, water quality; System control and protection and communication features can further realize normal operation of HVDC system core components and is also stable operation basis of HVDC circuit.
Technical characteristics
Depending on the converter valve characteristics and structural features to adopt a different process option;
It adopts non-renewable mixed bed ion exchange resin with special mixed ratio to purify cooling water to adapt the long-term stable operation at high temperature;
Redundancy set for key components (power supply, the main circulating pump, ion exchange, temperature-controlled three-way valve, sensors, PLC controller, communication lines, etc. );
It equips with independent degassing tank efficient automatic exhaust valve to realize effective water and gas separation;
It tracks change in the load converter valve and the ambient temperature change closely; Multi-stage temperature control logic design can keep the cooling water temperature at a stable range;
Electromagnetic compatibility design which is applicable for working conditions of converter stations;
It can communicate with host computer via combination of bus communication and to realize remote control.
