Abstract

The invention provides a complete redundancy testing apparatus control system of a direct-current valve cooling unit. The complete redundancy testing apparatus control system consists of two sets of programmable logic controllers, four sets of input / output modules, an acquisition measuring system, a synchronization module, a redundancy human-machine interface system, and a redundancy power supply and distribution system. According to the control system, complete redundancy configuration of software and hardware including hardware configuration, system power supply, main equipment control, instrument monitoring, signal acquisition processing, a human-machine interface, remote communication, operation data, parameter value setting, fault determination, and time-delay alarming and the like is realized. All electromechanical units and the sensor of the system are monitored and work automatically by a PLC; and instant exchange of the human being and the machine can be realized by a friendly interface of an MP operation panel. Operation parameters and alarm information bars of the system are transmitted to a main controller instantly; and the direct-current valve cooling unit can be operated and controlled remotely by the main controller, thereby realizing seamless joint of the valve cooling system and the host.

Description

technical field [0001] The invention relates to a control system of a DC transmission converter valve cooling system, in particular to a control system of a complete redundant test device. Background technique [0002] The DC valve cooling control system is the core equipment of the DC valve cooling system, but at present, the defects of the complete redundancy design of the DC valve cooling control system in each converter station are particularly prominent, which seriously affects the stable operation of the DC valve cooling system, causing huge economic losses, and urgently needs to be developed. Comprehensive research and system rectification, the process flow chart of the complete redundant test device of the DC valve cooling system is as follows figure 1 shown. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned prior art, and provide a control system for a complete test device of a DC transm...
