摘要： A digital arrangement for controlling a gas or steam turbine in which operating parameters of the turbine are sensed at a regular rate. Control parameters are then calculated from the operating parameters by at least one control and regulating program with predetermined reference values. The turbine is controlled and monitored in operation, in accordance with the calculated control parameters for the purpose of safeguarding against excess speed or surging. At least two computer systems are operated in parallel and at different speeds, and communications prevail between these two computer systems. The first of the computer systems is operated at a substantially rapid rate and with a limited supply of commands, together with an individual control and regulating program having a set of reference values. The second computer system is operated at a slower rate than the first computer system and with a greater supply of commands. The second computer system is operated with a plurality of control and regulating approaches and sets of reference values. Predetermined operating parameters are acquired by the first computer system for calculating control parameters and transmitting the calculated control parameters to the turbine. A new control and regulating program is selected by the second computer system when operation of the turbine is changed.

摘要： A turbomachine has a first process control element, a second process control element, and a test system for testing the first process control element. The first process control element and the second process control element influence the same process variable. To test the first process control element, the test system changes the process variable by means of the second process control element. This change in the process variable caused by the second process control element is compensated again by means of the first process control element.

摘要： A process is provided for protecting stored operating data of machinery or similar equipment. The operating data are stored by means of a computer system belonging to a control system or by means of a similar computer system belonging to the equipment and wherein the operating data are acquired continuously in the form of data sets and stored in a data storage medium for later analysis. A security code is generated with the storage of a data set from the currently stored operating data on the basis of parameters (k, l, m, n) of a preset determination rule and stored in the computer system. A comparison code is determined in at preset time intervals on the basis of the same determination rule from the operating data currently recorded in the data storage medium for verifying the operating data currently present in the data storage medium. The comparison code is compared with the security code generated originally, and a warning signal is generated or a protective action is triggered in a fourth step in case of a deviation between the comparison code and the security code generated originally.

摘要： An anti-surge control of a turbocompressor includes a controller which controls the progressive opening or closing of a blow-off valve as a function of the working point location relative to a blow-off line defined in the characteristic field. A quick opening of the blow-off valve upon the occurrence of a close approach to surge is effective by applying a correction signal to the integral section of the controller.

摘要： A method for preventing surges in a turbocompressor which supplies downstream processor with a gaseous medium by regulating a blow-off valve. The compressor volumetric intake flow is continuously measured, as is the compressor outlet pressure. A first minimum is designated to the compressor volumetric intake flow, and this minimum is dependent on the compressor outlet pressure. The blow-off valve is opened to ensure that the volumetric intake flow of the compressor remains above a surge limit when the intake flow drops to or below the first minimum and to a value that is still permissible and above the surge limit. The flow to the processor downstream is measured separately and in vicinity of the processor intake. The blow-off valve is also opened when the flow to the processor drops below a permissible second mininum value. The compressor intake flow is measured in vicinity of the compressor intake, whereas the flow to the processor is measured separately in vicinity of the processor intake. Each measuring location detects first any operating disturbances that originate at the respective location, so that the disturbances are detected quickly independent of the location where they originate.

摘要： Method of filtering both noisy and fluctuating input signals for a controller which is used for controlling the operation of a turbo compressor comprises obtaining an input signal from the operating device and before delivering an input signal to the controller correcting these signals through a filter whose time constant is small in one direction for example a decreasing or increasing signal amplitude directed toward the pumping limit of the operating device whose time constant is great in the other direction increasing or decreasing signal amplitude particularly away from the limit being controlled. Advantageously the filtered signal is compared with an unfiltered signal and the time constant of the filter is set as the function of the magnitude and the sign of the difference between the filtered and unfiltered signal. In addition the time constant may be reduced to a permanently pre-selected value possibly to zero when a switching threshold in a limit stages unilaterally exceeded. To be going below a switching threshold the time constant may be reset to the original time constant either immediately or after the constant is offset by hysteresis threshold.

摘要： An improved method of cooling compressed gases intermediate successive compressive stages in a multi-stage intercooled compressor system without forming condensate is provided. Cooling water flow to an intercooler intermediate successive compressive stages is regulated as a function of the actual temperature of the gas downstream of the intercooler and a set point temperature generated as a function of a linear approximation relating the inlet dew point temperature and the pressure of the gases downstream of the intercooler.

A first or local programming device is connected to the control and regulating system via a programming line. A monitor is provided for displaying the operating data and programs, as well as a keyboard for entering control commands and programming instructions are connected to the said first programming device. A second or remote programming device, located in a central control station or development laboratory and likewise equipped with a monitor and a keyboard, is connected to the first programming device via a long-distance data line.

摘要： A system (method and apparatus) are disclosed for detecting pressure surges in a turbo-compressor. Either the gas flow rate or gas velocity is measured at the intake or the outlet port of the compressor to produce a signal X. The rate of change of this signal X is determined and represented by a signal Y. The occurrence of surge is sensed and indicated by an output signal Z when the signal Y exceeds a prescribed threshold value.
