Example is applied only for explanation the utility model, rather than in order to limit protection domain of the present utility model.
As shown in figure 1, flexible direct current transmission control protection system, including operations staff's work station and control protected host,
Control protected host to include system-level control module, transverter level control module and current conversion station protection module, control protected host
It is connected by LAN nets with operations staff's work station, control protected host is connected by measuring bus with direct-current measuring device, is controlled
Protected host connects alternating-current field interface by bus, and alternating-current field interface is connected with DC fields interface by bus, and the control is protected
Shield main frame is also connected with valve arrangement.
Flexible direct current transmission control protection system of the present utility model, can realize that the interaction of data is very smooth, and control is protected
Protect interface of the main frame externally with valve control system concisely clear, safe and reliable, such global design switches in the absence of multilevel device
Problem is followed, sane system can be put into rapidly in the event of an anomaly, the multistage switching of complexity will not be formed, can be dropped significantly
Low device switches and causes the probability of system shutdown extremely, in addition, global design greatly reduces system layer, reduces interface
Risk, improves the availability of system, reduces failure and stoppage in transit probability.Analog quantity and digital measurement needed for global design connect
Half when mouth is only split, interface is succinct reliably, avoid meaningless repetition, and the effectively save investment of energy.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, and without departing from the objective and scope of the technical program, it all should
Cover among right of the present utility model.
