Xing-An HVDC Project occurred several times system outages caused by the filter blocking on the valve cooling system fault since December 2008.To find out the reasons leading to block
the configuration of the valve cooling system Xing-An HVDC Project was introduced and the reasons leading to scale in the valve cooling system were analyzed the Principle causes.Also recommendations for improvement based on engineering design deficiencies were made.Final settlement of the reasons was put.In order to achieve the main filter to prevent blockage caused HVDC system outage purpose
targeted preventive actions were put forward well which can improve the reliability
