摘要： A system and method for anticipating and controlling overspeed in a combined cycle turbine of the type having a gas turbine with a fuel flow control valve and a steam turbine with at least one steam control valve both disposed on a single shaft and having a heat recovery steam generator heated by said gas turbine and connected to supply steam to the steam control valve, the combined cycle turbine having a unified control system and driving a load. Below a preselected shaft speed the gas turbine fuel command signal controls power. Above the preselected shaft speed the steam turbine speed signal also controls power. Anticipation of overspeed under severe transient load changes, such as loss of electrical load, is provided by a power load unbalance system, wherein gas turbine power and steam turbine power responsive signals are summed after proportionately scaled power responsive signals exceed load by a preselected amount, whereby appropriate action is taken to reduce power before significant overspeed can occur.

摘要： An apparatus for preventing a turbine from exceeding a predetermined value of a monitored physical magnitude, the apparatus including an over-center toggle lever (3) pivotally mounted on a pivot point (6) on a stationary frame (7), the lever being capable of occupying a tripped position or a released position. In the cocked position, one arm (4) of the lever (3) presses against a stop (8) provided with a unit (20) which controls steam admission units to the turbine, the lever (3) moves away from the stop, steam is cut off, while the end (14) of the other arm (5) is pivotally mounted on the end of a connecting rod (10) which is pivotally mounted at its other end on a pin (11) which is integral with a piston (12) which a spring (16) pushes away. A mass (2) strikes the lever (3) which moves to the tripped position if the monitored magnitude exceeds the predetermined value. Due to the fact that the frame (7) and apparatus assembly is resilient, the lever can be tripped even if the piston (12) seizes in the associated cylinder (15). The apparatus of the invention is a high-security apparatus.

摘要： An overspeed protection controller (OPC) which is incorporated as part of a turbine speed/load control system for the purposes of controlling the monitored speed of a steam turbine at a first predetermined speed valve subsequent to an OPC activation is disclosed. The governor and interceptor valves of the steam turbine are positioned controlled by a set of electrohydraulically operated valve position servo systems. The OPC provides for rapid hydraulic closure of each valve when activated by either a detection of an interruption of generated electrical power flow to a power system load when the generated electrical power is greater than a predetermined value or the detection of the monitored turbine speed being greater than a second predetermined speed value. The rapid closure of the valves results in an interruption of steam flow to the high and lower pressure turbine sections of the turbine system which causes steam energy to be trapped in the reheater which is disposed between the turbine sections. The OPC is deactivated subsequent a predetermined time interval after the detection of generated power interruption when the monitored turbine speed is no longer greater than the second predetermined speed value. In response to the deactivation, the OPC controls the rotating speed of the turbine by positioning the interceptor valves to admit steam from the reheater to the lower pressure turbine sections in accordance with a continuous function based on the difference between the monitored turbine speed and the first predetermined speed value. Thus, the trapped steam energy in the reheater is utilized for keeping the turbine at the first predetermined speed value to permit rapid resynchronization of the turbine system with the power system load.

摘要： An electric power plant having dual turbine-generators connected to a steam source that includes a high temperature gas cooled nuclear reactor. Each turbine comprises a high pressure portion operated by superheat steam and an intermediate-low pressure portion operated by reheat steam; a bypass line is connected across each turbine portion to permit a desired minimum flow of steam from the source at times when the combined flow of steam through the turbine is less than the minimum. Coolant gas is propelled through the reactor by a circulator which is driven by an auxiliary turbine which uses steam exhausted from the high pressure portions and their bypass lines. The pressure of the reheat steam is controlled by a single proportional-plus-integral controller which governs the steam flow through the bypass lines associated with the intermediate-low pressure portions. At times when the controller is not in use its output signal is limited to a value that permits an unbiased response when pressure control is resumed, as in event of a turbine trip.

摘要： A shaft of a turbo jet carrying the rotor of a turbine and receiving apparatus which applies to the shaft an axial thrust which is greater than that of the turbine and directed in the opposite direction, and supported in bearings of which one, acting as the thrust bearing, is located adjacent to the turbine and is mounted in a support which is translatorily movable and is held in abutment in the direction of the thrust of the receiving apparatus in such a way that in the case of a fracture of the shaft, the bearing is displaced by the thrust of the turbine until the rotor blades engage frictionally the stator vanes, thereby braking the turbine and preventing the risk of a disintegration of the turbine.

摘要： The disclosure relates to a steam turbine-driven electrical generating plant wherein a protection system is provided for preventing the turbines from reaching speeds which would result in damage to the turbines; such speeds resulting from a sudden partial or entire loss of the electrical load. A partial loss of the load is sensed by a comparison of the inlet pressure at the lower pressure turbine stages with the output power provided to the load. If the output power decreases according to a predetermined relationship and if the input pressure corresponds to a value above a predetermined percentage of rated load, the interceptor valve is closed for a predetermined period of time to stop steam flow between the steam reheating apparatus and the lower turbine stages and thereby to reduce turbine speed buildup during and up to the time that additional load is connected to the generator output. In the event of a total load loss, which is determined in the same manner as in the case of a partial loss of the load but with the additional criteria that the circuit breakers associated with the generator be opened, both the intercept valve and the main governor valve, which regulates the steam through the high-pressure turbine stages, are closed. Whenever the speed of the turbine generator exceeds a predetermined percentage of rated speed, an overspeed protection system maintains both the interceptor valve and the governor valve in a closed position and cooperates with the main governor valve control system to relieve steam pressure within the reheating apparatus.
摘要翻译：本发明涉及一种蒸汽涡轮机驱动的发电设备，其中提供保护系统以防止涡轮机达到将导致涡轮机损坏的速度; 这种速度是由电负载的突然部分或全部损失引起的。通过将低压涡轮级的入口压力与提供给负载的输出功率进行比较来检测负载的部分损失。如果输出功率根据预定关系而降低，并且如果输入压力对应于高于额定负载的预定百分比的值，则拦截阀关闭预定时间段以停止蒸汽再加热装置与下部蒸汽加热装置之间的蒸汽流动涡轮级，从而在附加负载连接到发电机输出的期间和之前降低涡轮机速度的积累。在总负载损失的情况下，其以与负载的部分损失的情况相同的方式确定，但是具有与发电机相关联的断路器的额外标准被打开，拦截阀和主体调节通过高压涡轮级的蒸汽的调节阀被关闭。每当涡轮发电机的速度超过额定转速的预定百分比时，超速保护系统将拦截阀和调速阀都保持在关闭位置，并与主调节阀控制系统配合，以减轻再加热装置内的蒸汽压力。
