Title: POWER SUPPLY METHOD OF COLD-STATE FUNCTION TEST IN NUCLEAR POWER PLANT
Abstract:
A power supply method of a cold-state function test in a nuclear power plant. The power supply method comprises: sequentially operating three main pumps respectively used for heating a loop and circulating loop fluid, and limiting loads of equipment positioned on the same incoming lines with the operating main pumps; when an auxiliary power supply loses power, a diesel engine automatically started on one incoming line driving an upper charging pump, an equipment cooling water system, an important factory water utilization system and a residual heat discharge system on the corresponding incoming line, supplying power for an uninterrupted power supply on the same incoming line, and supplying power for an uninterrupted power supply on another incoming line through patching, so as to supply power for instrument control equipment, an upper charging pump 1 being arranged on an incoming line A, and an upper charging pump 2 and an upper charging pump 3 being arranged on an incoming line B. By means of the technical solution, under the condition that a main power supply is unavailable, the construction progress of a nuclear power project is not affected, and safety of tests and equipment is ensured.
