Title:
HYDRAULIC LOAD HIERARCHICAL CONTROL SYSTEM AND METHOD FOR INDIRECT WAVE ENERGY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/179803
Kind Code:
A1
Abstract:
A hydraulic load hierarchical control system and method for an indirect wave energy apparatus. The system comprises a first hydraulic cylinder group (1), a second hydraulic cylinder group (2), a third hydraulic cylinder group (3), a high-voltage energy accumulator group (4), a pressure detection control module (5), a first hydraulic generator set (6), and a second hydraulic generator set (7) and a third hydraulic generator set (8). A detection end of the pressure detection control module (5) is used for acquiring an internal pressure of the high-voltage energy accumulator group (4) and comparing the internal pressure with a preset pressure level. The on-off of reversing valves (204, 304) and electromagnetic valves (601, 701, 801) are controlled according to a comparison result.
