Control Communications Two Modbus ports, to be used as control interfaces. The protocol can be either ASCII or RTU and the communications can be RS-232, RS-422, or RS-485. One computer (PC) port to be used for program configuration storage. An overview of the 505E functions is shown in Figure 1-1. Use this block diagram to match the control features to the site-specific application required.
The 505E Digital Governor is designed to control extraction, extraction/ admission, or admission steam turbines. The difference between these turbines is the capability of the turbine to allow low pressure steam, which is at a lower pressure than the inlet, to enter and/or exit the turbine. An extraction turbine allows the lower pressure (extraction) steam to exit the turbine only and will have a non-return valve in the extraction header/line to prevent steam from entering the turbine. An admission turbine (also called induction) will allow excess header steam to enter the turbine through the low pressure inlet. An extraction/admission turbine will allow low pressure header steam to enter or exit the turbine depending on system pressures. A turbine with admission capability will have a stop valve or trip-and-throttle valve in the low pressure line to prevent steam from entering the turbine when the unit is tripped. The type of turbine used will depend on the system requirements and must be designed by the turbine manufacturer to perform the functions required. The 505E has two independent control channels available, the speed/load and auxiliary controllers. The outputs of these two controllers are low-signal-selected (LSS) to provide to speed/load demand signal to the ratio/limiter.
In addition to these channels, the speed/ load controller can be manipulated by another controller, the cascade controller. The cascade controller is ‘cascaded’ into the speed controller, whereby the speed controller setpoint is changed directly by the cascade controller output. The auxiliary controller can act as either a control channel or as a limiting channel. All three of these PID controllers have the option of utilizing an analog input signal to remotely position their setpoints. Additional features of the 505E include frequency control, isochronous loadsharing, critical speed avoidance, idle/rated control, and an automatic start sequence. There are two serial communications ports which can be used to monitor and control the turbine using Modbus protocol.
