Definitions
- the invention relates to an automatic control for a power plant with several, interacting plant parts. with different in the plant parts Community • sa s automation system functions aus ⁇ practicing automation devices, wherein the Automatisie ⁇ approximately devices together and are connected to a host unit via a data bus which transmits plant-relevant data of the.
- the automation system comprises a number of automation devices which communicate with one another and with a control unit via a common data bus.
- the automation devices can be constructed from both freely programmable and memory-programmed processors and each control and monitor several component groups or subsystems of the individual system parts.
- the invention is therefore based on the object of specifying an automatic control for a power plant, which is largely simplified and in all operating phases, that is to say when starting up and shutting down the system, and in the event of an irregularity or disruption of the process sequence, reliable guidance and Monitoring of the system guaranteed without overloading the operating personnel.
- each functional unit corresponding to a functional chain that comprises several sub-functions, and each sub-function comprises multiple subsystems with controllable system components.
- the various functional units, functionally implemented by the function chains, are media and energy transport processes taking place within logical process sections between process-technical breakpoints or conversion points.
- the function chains are expediently linked in a predetermined sequence during the start-up process and the shutdown process of the system.
- the automation devices of the various function chains communicate with one another, so that in terms of process technology, the individual functional units are only activated when the superordinate units are made available. In the meantime - while the system is operating - the function chains can be controlled individually.
- the function chains are advantageously linked to one another and to the data bus via data lines with coupling elements acting in a data-selective manner.
- data relevant only for a functional unit are advantageously transmitted.
- the subfunctions within a function chain are linked via a common data line.
- the overall process of the system can advantageously be controlled by only six function chains.
- These six function chains are hierarchically organized according to the logical process flow of the system in the following order: supply, disposal, transport of process waste heat and return transport of condensate, transport of process heat, conversion of primary energy into thermal energy, and conversion of thermal energy into electrical energy Energy.
- the advantages achieved by the invention are, in particular, that by dividing the overall process of a power plant into only a few logical process sections, each of which represents a functional unit, and by structuring the required functions accordingly a high degree of automation is achieved in function chains with an extremely high information compression on only a few status messages to be observed. As a result, the entire process of a power plant can be controlled and monitored by only one person in each operating phase.
- Figure 1 shows the automation structure of a power plant with multiple function chains
- FIG. 1 shows a number of function chains 1 to n, which are connected to one another via a common data bus 5 and to a control unit 16 or a block controller assigned to the control unit 16, if the power plant has several blocks.
- the individual function chains 1 to n comprise a plurality of subfunctions 7, which are performed by, for example, two automation devices 8.
- Each subfunction 7 are subsystems 9 of individual system parts, e.g. assigned to a boiler, a turbine group or a condenser.
- a subsystem 9 here is a liquid container 10, to which a line 11 with a pump 12 and a valve 13 is connected. Liquid can be supplied to the container 10 via a line 14 with a valve 15.
- the subfunction 7 in this subsystem 9 comprises the automatic control of the valves 13 and 15 and the pump 12, symbolized by the control signals a, b and c, of parameters f and p to be controlled and monitored in part in cooperation, which here are the fill level of the container 10 or the pressure in the line 11.
- the subfunctions 7 of the function chain 1 are linked to one another via a data line or a data bus 20 through interfaces 21.
- data relevant only for an associated functional unit are preferably transmitted.
- the functional units represented by the function chains 1 to n
- the functional units are successively activated and kept in operation by a control command.
- the automation devices 8 assigned to the function chains 1 to n are coupled to one another and via data lines 25 and data-selective coupling elements 26 to 29, for example intelligent bridges linked to the data bus 5.
- the coupling elements 26 to 29 transform the individual function chains 1 to n into local data transmission units, between which only individual status signals are transmitted.
- the control command "start-up" first activates the function chain 1. Only when the function chain 1 is ready, does a corresponding status signal of the function chain 1 pass the control command on to the function chain 2 via the coupling element 27. In a corresponding manner, the function chain 3 is only activated when the function chains 1 and 2 are ready.
- FIG. 2 shows a signal flow diagram of the automatic control of a block of a power plant with an overall process divided into six functional units.
- the function chains 1 to 6 corresponding to the functional units are organized hierarchically in a logical order.
- the individual function chains 1 to 6 are assigned the automation devices 8 which perform various functions in a common automation system, in accordance with the technological structure of the system.
- function chain 2 comprises four subfunctions 7, also symbolized by arrows.
- function chain 3 the required for the transport of process waste heat and the return transport of condensate
- Such control interventions for example in the condenser of a water / steam circuit of a steam turbine consisting of several system parts, are carried out and monitored automatically.
- the function chain 5 performs the functions required for a "conversion of primary energy into thermal energy".
- the subsystems 9 of a gas turbine combustion chamber also shown schematically, are put into operation.
- a control command triggered in the control unit 16 is forwarded to the individual function chains 1 to 6 via a block control unit 30. If the subsystems 9 assigned to the function chain 1 are put into operation, a control signal is transmitted from the function chain 1 to the function chain 2, which together with the control command pending on the function chain 2 sets the subsystems 9 of the function chain 2 in operation.
- Function chains 3 to 6 are activated in succession in a corresponding manner. When the system is shut down, the function chains 6 to 1 are run through in reverse order and the corresponding process sections are deactivated one after the other.
- the subsystems 9 of the individual function chains 1 to 6 can be controlled individually via the corresponding automation devices 8.
- the control takes place in the control unit 16 by touching a screen 31 designed as a plasma display, which is arranged in a control panel 32. Feedback, status reports and fault messages are visualized on screens 33, which are also built into the control panel 32.
- control panel 32 is designed in the shape of a circular arc, corresponding to a cockpit.
