A turbine-governor performance analyzer
Electrical Engineering, 1941IN the modern interconnected power system the steam turbine governor plays a very important role. Its performance has an important bearing on system stability, effect of load swings, tie line load control, frequency regulation, and other related phenomena.

Journal of Fluids Engineering, 1940
Abstract This paper has been prepared as a contribution to a symposium on the subject of steam-turbine governors. The importance of the subject at present arises more from the increasing complexity of interconnection requirements than from any definite deficiency in existing apparatus.

Proceedings of the Institution of Mechanical Engineers, 1953
In this paper is presented a general picture of closed-sequence system controls of hydro-electric plants, covering the relation between water-turbine governors and water level, power, frequency and tie-line controls. Special mention is made of the difficulty of governing created by the inertia of the water in the pipe-line.

Solving turbine governor instability at low-load conditions
2015 IEEE Petroleum and Chemical Industry Committee Conference (PCIC), 2015During routine commissioning of a steam turbine load-sharing system, serious low-load frequency instabilities were discovered. These instabilities were causing undamped oscillations in power and frequency to escalate until protective relays tripped a generator offline.

Computer-Aided Design of Adaptive Hydraulic Turbine Governors
IFAC Proceedings Volumes, 1979Abstract The design of the speed control system for a hydroelectric power unit, connected to a local grid is investigated. Manual design methods are limited to very simple process models. If more adequate models are to be need routinely, an interactive computer-aided control system design procedure is necessary.

Turbine governor system frequency measurement based on DSP
2011 2nd International Conference on Control, Instrumentation and Automation (ICCIA), 2011Hydro turbine governor play an important role in maintain the frequency stability of power system and operation control. It also affects security and efficiency of the hydropower plants. So performance of the governor is important to the hydropower plants. Frequency measurement is the key problem in the hydro-turbine governing system.

Microprocessor-Based Fault-Tolerant Nuclear Turbine Governor
IEEE Transactions on Nuclear Science, 1986A new microprocessor-based fault-tolerant nuclear turbine governor has been developed. Hierarchically distributed configuration and asynchronous triplicated architecture with middle value voting logic maximizes the plant availability. Problem-oriented language is provided for design ease and program maintenability.

Integrated maintenance features of hydro turbine governors
Proceedings. International Conference on Power System Technology, 2003Governor is one of the most maintenance intensive equipment in hydro power plants. The maintenance computerization of the governor is studied. A knowledge bank, which summarizes both the expert knowledge and the analytical knowledge on the failure modes and their manifestations as well as their effects, is established.

Robust control of hydro turbine speed governor
Proceedings of the 10th World Congress on Intelligent Control and Automation, 2012This paper presents the design of the μ robust performance of a hydro Turbine speed governor. It can be used to solve the μ robustness problems, which can't be done by the conventional H ∞ robust performance designs. High frequency oscillation and large amplitude of output and control variable of the control system are exhibited by a conventional H ∞
