Title:
ENERGY CONVERSION SYSTEM, OVER-TEMPERATURE OPERATION CONTROL METHOD THEREOF, AND CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/035707
Kind Code:
A1
Abstract:
Provided are an energy conversion system, an over-temperature operation control method thereof, and a control apparatus (00), comprising: in accordance with the operating temperatures of at least two power modules, determining an over-temperature module and at least one non-over-temperature module; obtaining a derated operating power and a power derating difference value for the over-temperature module, and, in accordance with the power derating difference value, determining at least one increased-rating operating power, wherein the increased-rating operating power corresponds one-to-one to a non-over-temperature module; on the basis of the at least one increased-rating operating power, determining whether the system satisfies a preset no-derating operating condition; if the system satisfies the preset no-derating operating condition, then driving the over-temperature module to operate in accordance with the derated operating power, and driving the non-over-temperature module(s) to operate in accordance with the increased-rating operating power. By reducing the operating power of the over-temperature module, the temperature thereof is lowered, and by increasing the operating power of a non-over-temperature module, the overall power of the system can be kept unchanged, which is beneficial to improving system safety performance and power generation.
