The invention relates to an automatic water supplementing system suitable for a flexible direct-current converter valve cooling system. The automatic water supplementing system comprises a converter valve heat exchanger, and a seawater lifting pump, a seawater filter, a seawater desalination device and a deionized water device which are communicated in sequence; a fresh water make-up pump is arranged on the seawater desalination device; a deionized water make-up pump is arranged on the deionized water device; the fresh water make-up pump is connected with one loop pipeline in the converter valve heat exchanger; the deionized water make-up pump is connected with the other loop pipeline in the converter valve heat exchanger; a first pressure stabilizing device is arranged in a pipeline through which the fresh water make-up pump is communicated with the converter valve heat exchanger; the fresh water make-up pump is in signal connection with the first pressure stabilizer; a second pressure stabilizing device is arranged in a pipeline through which the deionized water make-up pump is communicated with the converter valve heat exchanger; and the deionized water make-up pump is in signal connection with the second pressure stabilizing device. The first pressure stabilizing device and the second pressure stabilizing device respectively control the fresh water make-up pump and the deionized water make-up pump to make up water, and automatic water make-up of the cooling system is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of cooling systems for flexible DC converter valves, and in particular relates to an automatic water supply system suitable for cooling systems for flexible DC converter valves. Background technique [0002] Offshore wind power resources are abundant, the development process is pollution-free, and does not occupy land resources, so it has great development prospects. my country has a vast territory, including a sea area of more than 3 million square kilometers and a coastline of 18,000 kilometers; with the continuous development and maturity of offshore wind power technology, more offshore wind energy resources will be available. [0003] Offshore wind power generation facilities usually include a converter station, which is used to solve the heating problem of electrical equipment such as converter valves and connecting pressure balls in offshore wind power generation facilities; in the converter station,...
