Abstract
The utility model relates to a power station air compressor control system, which comprises an air storage tank for providing an air source, wherein the air storage tank supplies air to a plurality of air compressors for braking a power station water turbine, each air compressor is connected with a PLC (programmable logic controller) through a soft starter, and a pressure transmitter is arranged on the air storage tank and is connected with the PLC. The starting and the stopping of a plurality of air compressors are automatically controlled through the PLC, when the pressure of the air storage tank is reduced to a certain value, one air compressor is automatically started, when the pressure is continuously reduced to a certain value, another air compressor is automatically started, when the pressure is raised to a certain value, the air compressor is automatically stopped, and when the air compressor has fault, the fault air compressor can be automatically switched to another air compressor for operation. In addition, the operation of the air compressor can take turns according to the time and the number of times, the unattended operation is realized, the automatic control is realized, the work load of personnel is reduced, the work efficiency is improved, the abrasion of equipment is reduced, and the service life of the equipment is prolonged.
Description
Technical field
The utility model relates to Hydropower Plant, and the braking of water power plant water turbine is specifically controlled.
Background technique
At present, the braking of the water turbine of Hydropower Plant is general brings running resistance by the air compressor pressurized gas to compressor emergency shutdown, to reduce the compressor emergency shutdown time used.Existing braking control system mostly adopts manual Starting mode, when compressor emergency shutdown, needs gas in the braking gas holder to hinder the running of water turbine, during to certain pressure, needs operator manually boot brake air compressor when the gas holder pressure decreased.After pressure raises, manually stop air compressor.This mode not only automaticity is low, and working time that can not many air compressors of reasonable distribution.
The model utility content
For above-mentioned technical problem, the utility model provides a kind of automatic start-stop of air compressor and control system of rotation of realizing.
The technical scheme in the invention for solving the above technical problem is: the power station control system of air compressor, comprise the gas holder that source of the gas is provided, this gas holder is to several air compressor air feed of braking Power Station Turbine, and each described air compressor is connected with the PLC controller by a soft initiator; On described gas holder, pressure transmitter is installed, this pressure transmitter is connected with described PLC controller.
Further, on each described air compressor, a temperature transducer is installed, each temperature transducer is passed to described PLC controller with signal.
Further, described PLC controller is connected with a liquid crystal touch operation screen.
As can be known from the above technical solutions, the utility model is controlled the start and stop of multiple air compressors automatically by the PLC controller, during to certain value, automatically starts an air compressor when the gas holder pressure drop; When pressure continues to drop to certain value, automatically start another air compressor; When being elevated to certain value to pressure, automatically stop air compressor; Can automatically switch to another compressor operation after the mechanism of qi fault.And the operation of air compressor can be carried out rotation by time or number of times, realizes unmanned, automatically controls, and reduces personnel's workload, increases work efficiency, and reduces the wearing and tearing of equipment, the working life of extension device.
Description of drawings
Fig. 1 is system block diagram of the present utility model.
Embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail:
This control system comprises the gas holder 1 that source of the gas is provided, this gas holder is to several air compressor 2 air feed of braking Power Station Turbine, each described air compressor is connected with PLC controller 3 by a soft initiator 7, pressure transmitter 4 is installed on described gas holder, and this pressure transmitter is connected with described PLC controller.Described PLC controller is completed automatic measurement and control to pressure according to initialize program by pressure transmitter, realize the automatic start-stop of air compressor and the switching of blowdown valve and the work of several air compressors, the automatic switchover of standby operation state etc., to guarantee the normal operating pressure of gas holder.
As further improvement of the utility model, on each described air compressor 2, a temperature transducer 5 is installed, each temperature transducer is passed to described PLC controller with signal, this can judge according to temperature the runnability of air compressor, break down as air compressor, automatically switch to another air compressor.PLC controller 3 of the present utility model is connected with a liquid crystal touch operation screen 6, and the gas holder force value of native system and various running state can show on liquid crystal touch operation screen.
The utility model has been realized the switching of automatic start-stop and the blowdown valve of air compressor, and the automatic switchover of the work of two air compressors, standby operation state, guarantees the normal operating pressure of gas holder; Reduced the compressor emergency shutdown time used; make the equipment operation more economical; more reasonable; and communication of the present utility model adopts ripe communication modes and the upper-position unit in a distant place to carry out communication; central control chamber will be given on important information; make the operations staff constantly know field condition, automaticity is high, few man on duty.
Above-mentioned mode of execution is only for illustration of the utility model, and be not to be to restriction of the present utility model, the those of ordinary skill in relevant technologies field, in the situation that do not break away from the utility model spirit and scope, can also make various variations and modification, so all technological schemes that are equal to also should belong to category of the present utility model.
