  • Turbine control unit with a temperature load ⁇ regulator as a master controller
  • GB 2 074 757 A discloses a method and arrangement for controlling the thermal stress of components of a steam turbine at maximum load and unload speeds during startup, shutdown, and other periods of load change. From monitored and derived quantities, a load rate is calculated for each of several preselected turbine components and the lowest speed selected for control. At the same time the
  • US 2006/233637 AI shows a turbine start regulator with an optimum start control unit for predicting a thermal mix load, which is determined in a turbine rotor during a prediction period on the basis of the current time in the future to ⁇ , wherein a turbine acceleration rate and a load rate of growth can be used as control variables.
  • US 5,044,152 A shows a method for operating a combined power station with a gas turbine system and an evaporator, steam ge ⁇ neriert in which from the heat of the turbine exhaust gas and a steam turbine is fed, which is operated by the thus generated steam.
  • An inlet to the gas turbine system is controlled based on the condition of the evaporator or steam turbine.
  • a turbine control unit for Rege ⁇ development of a turbine in particular for controlling the start-ei ⁇ ner turbine proposed, which is designed as a cascade controller.
  • a regulator is understood to mean a cascade controller, wherein at least two control loops each other ge ⁇ are switched on. In this case an outer loop, a so- ⁇ -called master controller is present. It has the task of defining or at least influencing setpoints for an internal control loop, ie a downstream control loop.
  • the master controller thus has the task of predetermining or influencing the setpoint values for an internal control loop in such a way that an excessive temperature load is avoided. So far, when starting a turbine usually with a controller for the turbine power the Performance, more precisely regulated the performance increase. To avoid an excessive temperature stress, the temperature is measured and stopped at an excessive Temperbe pipeung startup. Thus, the performance increase is interrupted. Thus an excessive tempera ⁇ turbe pipeung of components is indeed avoided, but a loss of time is to be accepted until the turbine can reach the ge ⁇ wished performance.
  • a temperature stress regulator for the temperature temperaturbeanprüuchter components as a master controller can be achieved that the allowable temperature stress is largely used, so about the start of the power increase of the turbine turbine is as high as possible, without the ⁇ casual temperature stress of components to cry ⁇ th. It can so the power can be increased faster and a desired turbine performance can be achieved faster.
  • temperature stress regulator is still an internal controller available. The temperature load controller provides the internal controller with a suitable set point to ensure that the turbine is controlled so that it does not exceed a permissible temperature load.
  • the invention is primarily based on steam turbines in which the temperature stress, in particular the temperature stress during start-up represents a significant problem. However, it should not be ruled out that the invention is also used in gas turbines, for example.
  • the inner regulator is a turbine regulator, in particular a turbine power regulator.
  • turbine regulators are known in the art and are very well suited for the regulation of turbines, especially when starting the turbine.
  • the temperature load regulator will pass in this case the inner regulator a setpoint for the performance of the turbine. As will be discussed in more detail later, this may also be a target value for the increase in performance.
  • the main application is certainly the startup of a turbine. However, it is also conceivable to avoid overheating, for example, in full-load operation by the temperature-load regulator designed as a guide regulator.
  • a temperature-stress calculation unit is provided in order to predefine at least one desired value for the temperature-stress controller.
  • the temperature load calculation unit calculates, mostly from data stored in databases, whether a temperature increase is permissible.
  • the temperature load controller is designed to provide for such a regulation of the turbine such that a desired time-temperature rise, so a certain temperature increase per unit time ⁇ is not exceeded.
  • Decisive, in particular when starting the turbine is usually not an absolute ⁇ lute temperature should not be exceeded. It should not be forgotten that there is of course a temperature that must not be exceeded. During start-up, however, it is crucial to avoid undue material stresses that the temperature does not rise too fast. Therefore, the temperature regulator must normally ensure that the temperature does not rise too fast.
  • the temperature stress calculation unit can deduce a temperature rise from the detected temperature values and their time sequence. Furthermore, this temperature increase can be compared with stored data. This allows to determine if the temperature rise is increased can, must be lowered or remain the same. This information can be passed to the temperature stress controller. From this information, the temperature demand controller can generate a suitable setpoint for the inner controller.
  • the temperature- stress regulator is designed to avoid a temperature stress that is caused by temperature differences. Occasionally, a temperature stress also results from different temperatures within a component or from different temperatures of different components. For example, it can be problematic when blades of the turbine expand by heating and a casing of the turbine expands more slowly due to slower heating. It therefore sometimes applies temperature differences that trigger a temperature stress to recognize and avoid by a regulation.
  • the turbine power controller is configured to generate setpoints for positioners that control the position of control valves. The control valves significantly influence the respective amount of steam flowing through and thus the performance or performance curve of the turbine. In this embodiment, the turbine control unit is thus cascaded twice. First, the Temperaturbean ⁇ spruchungsregler is present as the parent master controller, the setpoints for the controller of the turbine power generated. The turbine power controller in turn generates setpoint values for the positioners
  • the turbine control unit is designed turbine stages, in particular a Hochdrucktur ⁇ bine, to regulate a medium pressure turbine and a low pressure turbine separated.
  • the performance can be increased differently, especially due to different Temperaturbeanspru ⁇ chungen.
  • usually a completely separate regulation can not be realized.
  • different steam paths are available, the boundary condition that steam flows from the high-pressure turbine into the medium-pressure turbine and from there into the low-pressure turbine may result in certain dependencies on the performance of the individual turbine sections. Nevertheless, it is advantageous to be able to regulate individual sub-turbines in principle separately. This allows about the Leis ⁇ tion of a sub-turbine to increase faster, while the performance of another sub-turbine is to increase slower to avoid undesirable temperature stress.
  • temperature sensors are mounted at different locations of the turbine, in particular on a high-pressure turbine and / or on a medium-pressure turbine.
  • a high-pressure turbine and the intermediate pressure turbine han ⁇ delt it is more temperature-stress components, so that temperature sensors are required, above all there. In many cases, it makes sense to install temperature sensors in the low-pressure turbine as well.
  • the invention also relates to a method of controlling a turbine with a cascade controller comprising a mecanicsreg ⁇ ler and an internal regulator, the master controller detects a temperature stress of the turbine and passes such setpoints to the inner controller, that a uner ⁇ desired temperature stress of the turbine is avoided , Further explanations of the method will be omitted here. Reference is made to the explanations of the turbine control unit described above, which may be used to carry out the method.
  • the master controller detects the temperature stress of the turbine by a temporal temperature increase, ie by a temperature increase per unit time, and determines the resulting temperature stress, wherein at too high a temperature stress to the inner controller the setpoint is passed to reduce the turbine power increase, the set point is passed at a temperature load within a desired range, the power increase can be maintained, and at a temperature load below a threshold the setpoint is passed to increase the power increase.
  • too high a temperature load here does not mean that the temperature stress is already unacceptably high. Too high a temperature load only means that a limit value for the control has been exceeded.
  • the regulation should just avoid an inadmissibly high temperature stress. This regulation allows the rapid start-up of a turbine without an inadmissibly high temperature stress.
