 Woodward 9907-165 505E Digital Governor The 9907-165 is part of the 505 and 505E microprocessor governor control units. These control modules are specifically designed to operate steam turbines as well as turbogenerator and turboexpander modules.  It is capable of actuating the steam inlet valve using the turbine's staged actuator. The 9907-165 unit is primarily used to control steam turbines by operating the turbine's individual extractions and/or intakes. The 9907-165 can be configured in the field by the on-site operator. The menu-driven software is controlled and changed by the operator control panel integrated into the front of the unit. The panel displays two lines of text with 24 characters per line. It is also equipped with a range of discrete and analog inputs: 16 contact inputs (4 of which are dedicated and 12 are programmable) followed by 6 programmable current inputs with a current range of 4 to 20 mA. The 505 and 505XT are Woodward's standard, off-the-shelf controller series for operating and protecting industrial steam turbines. These user-configurable steam turbine controllers include specially designed screens, algorithms and event loggers to simplify use in controlling industrial steam turbines or turboexpanders, driving generators, compressors, pumps or industrial fans.The Woodward 9907-165 505E digital governor is designed for precise control of extraction steam turbines and is widely used in power generation, petrochemical, papermaking and other industrial fields. The core function of this governor is to accurately manage the turbine speed and extraction process through digital control to ensure efficient and stable operation of the turbine under various operating conditions. It can balance the turbine output power and extraction volume, so that the system can maintain high operating efficiency while meeting production needs. It can accurately adjust the relationship between turbine speed and steam pressure, so that the turbine can still operate smoothly when the load fluctuates or the operating conditions change. It can optimize energy utilization and reduce waste, thereby improving overall economy and production efficiency. Through intelligent algorithms and rapid response mechanisms, the governor can respond to emergencies to maintain system safety.Frequently asked questions about the product are as follows: -What is the Woodward 9907-165? It is a high performance digital governor used to control the speed and power output of engines, turbines and mechanical drives. Its main purpose is to regulate fuel injection or other power input systems in response to speed/load changes. -What types of systems or engines can it be used with? It can be used with gas and diesel engines, steam turbines and hydro turbines. -How does the Woodward 9907-165 work? -The 505E uses digital control algorithms to maintain the desired speed, primarily by adjusting the fuel system or throttle. The governor works by receiving input from speed sensors and other feedback mechanisms, and then processing this data in real time to modify the output of engine power accordingly.
