Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and mode of execution of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, a kind of turbine-generator units complex control system, comprise control system main body, described control system main body comprises control chip, described control chip is connected with PT signal conditioning circuit and CT signal conditioning circuit, and described main control chip is also connected to I/O interface circuit, 4 RS485 communication interfaces, RS232 communication interface and 4 signal output module.The communicate existence that connects of described 4 RS485 is convenient to operational module in need with other at any time and is connected, mutual transmission of signal.Described I/O interface circuit ensure that signal is isolated, and makes the present embodiment only gather one group of required signal.
Described RS232 communication interface is connected with touch screen module, and described 4 signal output module are also connected to excitation con-trol module, speed-regulating control module, concurrent control module and protecting control module.
Described control chip is ARMSTM32F103 chip.
Described control system main body is provided with the LED for showing contact state and logical signal state; Described control system main body being also provided with for 18 of exporting input signal is the socket interface of a group, is convenient to maintain and replace, and equipment to connect line simple.
In the present embodiment, PT signal conditioning circuit comprises four voltage transformers in parallel; CT signal conditioning circuit comprises the current transformer of three series connection.Wherein, three voltage transformers gather one group of signal can pass to excitation module, speed-regulating control module, concurrent control module simultaneously, make three modules jointly use same group of data; Harmony is good, is not easy to occur error; Another one voltage transformer gathers the signal required for protecting control module.
The working principle of this enforcement is as follows:
(1) after unit integrated controller powers on and runs, first self-inspection is carried out, then carry out equipment state I/O signal, PT, CT transducer signal reads sampling, control chip is sent to after signal is nursed one's health, control chip reads the corresponding parameter of internal storage, deliver to touch screen to show, understand current turbine-generator units state for operator.
(2) staff performs start step; control chip fill order; according to actual signal parameter, combined operation is carried out to turbine-generator units: first speed-regulating control module sends power-on command; then excitation con-trol module execution start-up command carries out machine establishment pressure; simultaneous interconnecting is carried out finally by the module same period; after unit operation is normal, protecting control module comes into operation, and monitors run normal operational outfit protection.
(3) all devices Operational Limits, equipment state, all shown by touch screen module, observes supervision for operations staff.The control command of all staff on board can be sent to control chip by touch screen, is finally issued to the modules such as excitation, speed governing, protection and performs.
(4) controller possesses remote auto controlling functions, if user carries out telemonitoring and control beyond power station, controller COM1 can meet various communication protocol interface and export, unit parameter is carried out remote transmission, receive and perform remote control command, meet power station automation and scheduling far-end controlling functions.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on said structure design; for solving same technical problem; even if some making on the utility model are without substantial change or polishing; the essence of the technological scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
