Abstract
The many running statuses of a kind of generator unit represent method, and comprise the unit generation pilot lamp be arranged on the screen of imitation screen, described unit generation pilot lamp comprises red light, green light, amber light; When machine set outlet isolating switch and disconnector all close a floodgate and generating unit speed is greater than 95%, red light lights, and represents set grid-connection state; When generating unit speed is less than 2% and generator outlet disconnector disconnects, green light lights, and represents unit full cut-off state; When operator manually assign forbid power-on command and kept by program time, amber light lights, represent forbid open state; When generating unit speed is greater than 5%, simultaneously machine set outlet isolating switch or machine set outlet disconnector at least one when not closing a floodgate, red light and green light replace light on and off, represent unit transition state; When unit maintenance status command is assigned and kept, red light and green light extinguish, and represent unit maintenance state.The present invention makes computer supervisory control system can represent multiple operating states of the units by minority indicator light colors.
Description
Technical field
The many running statuses of a kind of generator unit of the present invention represent method, belong to computer supervisory control system field.
Background technology
At present, hydropower generator operating states of the units comprises multiple, as and net state, full cut-off state, forbid open state, transition state, inspecting state etc.The Generator Status pilot lamp that power station Central Control Room imitation screen screen (returning screen) adopts then only has a few instruction color, and the state that needs represent cannot be completely satisfied.For this reason, as long as need a kind of minority color can represent the method for various states, ensure that the state of instruction is accurate simultaneously, meet basic custom, intuitively easily recognize.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the many running statuses of a kind of generator unit and representing method, making computer supervisory control system can represent multiple operating states of the units by minority indicator light colors.
The technical scheme that the present invention takes is: the many running statuses of a kind of generator unit represent method, comprise the unit generation pilot lamp be arranged on the screen of imitation screen, and described unit generation pilot lamp comprises red light, green light, amber light;
When machine set outlet isolating switch and disconnector all close a floodgate and generating unit speed is greater than 95%, red light lights, and represents set grid-connection state;
When generating unit speed is less than 2% and generator outlet disconnector disconnects, green light lights, and represents unit full cut-off state;
When operator manually assign forbid power-on command and kept by program time, amber light lights, represent forbid open state;
When generating unit speed is greater than 5%, simultaneously machine set outlet isolating switch or machine set outlet disconnector at least one when not closing a floodgate, red light and green light replace light on and off, represent unit transition state;
When unit maintenance status command is assigned and kept, red light and green light extinguish, and represent unit maintenance state.
Work out operating states of the units calculation procedure in the LCU of described imitation screen, work out according to generator operating states of the units condition: set grid-connection state, unit full cut-off state, forbid open state, unit transition state, inspecting state computational logic; After the LCU operating states of the units calculation procedure of imitation screen is worked out, connect PLC I/O, imitation screen screen completes the state display of generator pilot lamp.
The many running statuses of a kind of generator unit of the present invention represent method, for representing generator unit five kinds of running statuses: and net state, full cut-off state, forbid open state, transition state, inspecting state.Described five kinds of generator set states are combined by the light on and off of yellow, green, red three kinds of LED and persistent state and realize.Make computer supervisory control system can represent multiple operating states of the units by minority indicator light colors.
Accompanying drawing explanation
Fig. 1 is set state instruction computational logic in PLC program of the present invention.
Embodiment
The many running statuses of a kind of generator unit represent method, comprise based on imitation screen LCU: local control unit, PLC: the power station computer monitoring system of programmed logic controller, be arranged on the unit generation pilot lamp on the screen of imitation screen, described unit generation pilot lamp comprises red light, green light, amber light.
1), in imitation screen LCU work out operating states of the units calculation procedure, according to generator operating states of the units condition establishment set grid-connection state, unit full cut-off state, forbid open state, unit transition state, inspecting state computational logic.
2), in imitation screen LCU operating states of the units calculation procedure, as shown in Figure 1,
A, when machine set outlet isolating switch and disconnector all close a floodgate and generating unit speed is greater than 95%; Employing outputs 1: output stablized by red light is 1, that is: red light lights, and represents set grid-connection state;
B, when generating unit speed is less than 2% and generator outlet disconnector disconnects, adopts and output 2: output stablized by green light is 1, that is: green light lights, represent unit full cut-off state;
C, when operator manually assign forbid power-on command and kept by program time, adopt output 3: it is 1 that amber light stablizes output, that is: amber light lights, represent forbid open state;
D, be greater than 5% when generating unit speed, simultaneously machine set outlet isolating switch or machine set outlet disconnector at least one when not closing a floodgate, adopt and output 1: red light and output 2: it is 1 that green light replaces output, that is: red light and green light replace light on and off, represents unit transition state;
E, when unit maintenance status command is assigned and kept, adopt and output 1: red light and output 2: it is 0 that green light exports, that is: red light and green light extinguish, and represent unit maintenance state.
3), after imitation screen LCU operating states of the units calculation procedure works out, connect PLC I/O, imitation screen screen completes the state display of generator pilot lamp.
