Abstract

The invention discloses a control system for a hydrostatic energy storage type hydraulic transmission type wind power generator set. The control system comprises operation layer, a executive layer anda control layer; the operation layer comprises an industrial personal computer and a PLC control system; the executive layer comprises a main control module and multiple sub-control modules; the control layer comprises multiple working systems of a hydraulic type fan generator system; the industrial personal computer is used for displaying working states of the multiple working systems and sending control instructions to the PLC control system; and the PLC control system is used for responding to the control instructions and calling the multiple sub-control modules through the main control module to control the multiple working systems. According to the control system, through different levels and division of the different functions of the sub-control modules, confusion of the execution process of the PLC control system is avoided, so that the sub-control modules divided by the functions of the system are independently operated, and no influence is generated among the sub-control modules.

Description

technical field [0001] The invention belongs to the technical field of hydraulic control systems, and in particular relates to a PLC control system for a hydrostatic energy storage type hydraulic transmission type wind power generating set. Background technique [0002] Traditional wind generators mainly adopt a gearbox structure, which mainly includes wind rotors, main shafts, gearboxes, generators and power electronic components. [0003] With the continuous advancement of technology, hydraulic wind turbines have emerged, which mainly include wind rotors, main shafts, hydraulic pumps, high-pressure pipelines, low-pressure pipelines, accumulators, hydraulic motors, generators and loads. The hydraulic wind turbine is quite different from the traditional gearbox structure generator, which makes it difficult for the control mechanism of the traditional generator to be applied to the hydraulic wind turbine. [0004] At present, the system structure of hydraulic wind turbines h...
