A novel technique to estimate and model rotorbody parameters of a large steam turbine-generator from real time disturbance data is presented. For each set of disturbance data collected at different operating conditions, the rotor body parameters of the generator are estimated using an Output Error Method (OEM). Artificial neural network (ANN) based estimators are later used to model the non-lin...

Abstract In developing the PeLUIt 150 MW nuclear power plant based on High Temperature Gas-cooled Reactor (HTGR) technology, with helium-coolant and output thermal of MW, simulator is also developed for training operators educating other technical personnel. Referred to balance (BOP) design PeLUIt, utilized vPower simulation platform simulate secondary loop generation a water-steam Rankine cycl...

This work presents a comparison study between the state-space and polynomial methods for the design of the robust governor for load frequency control of steam turbine power systems. The robust governor is synthesized using the two approaches and the comparison is extended to include time and frequency domains performance, controller order, and uncertainty representation, weighting filters, opti...

This paper shows how to use Markov Decision Processes to guide the actions of the operation personnel during a transient in a heat recovery steam generator (HRSG). The critical events shown correspond to situations where a strong participation of human operators is required. The aim is to help the steam generation control system to set the plant on a safe operation state. The proposed system al...

1. ABSTRACT: The US Military needs reliable, secure, and low-environmental impact sources of base and shore power for its installations. US Navy ships need generating systems for main propulsion, on-board power, catapults, heat/air conditioning, and other applications. These needs can be met with a unique, drive-gas generator that produces a high enthalpy mixture of high purity steam and carbon...

In this paper, a numerical scheme has been developed for primary and secondary fluids adopting Euler–Cauchy method to find the temperature distribution of the primary fluid relative to the secondary fluid and vice–versa and to obtain an optimum boiling length of the tube in the vertical inverted U–tube steam generator (UTSG).
