“…The parameter testing of the steam turbine speed regulating system is to test and identify the key parameters in the model by utilizing the original standardized data and the model simulation test to provide precise parameters for the power grid stability analysis [4] . The acquisition method of above-mentioned parameters of the integrate model includes: control logic verification, material gathering and simulation fitting of actual measured data.…”

At present, power system stability analysis model usually adopt the BPA model, which is provided by the PSD-BPA Transient Stability Program User Manual, and the model parameters are usually obtained from the measured data of 80% or more typical working conditions. With the expansion of load operating interval after retrofitting the flexibility of thermal power units, whether the model parameters can accurately simulate the response changes of the power system under the working conditions of deep peak regulation, that is, the model adaptability under the working conditions of deep peak regulation needs to be further studied. In this paper, the measured data of a 660MW subcritical unit under the working conditions of deep peak regulation was simulated and identified through the model. After the analysis of the simulation results, it was found that the model parameters under the working conditions of deep peak regulation greatly deviated compared with those under typical working conditions, so the model’s adaptability was poor.

“…Since the critical position of the speed governing system in energy production is well known by the sector representatives, even a standard has been revealed in this context (IEEE, 2007(IEEE, , 2011. Also, simulation of the speed controller and valve correlation were realized (Zhu et al, 2021).…”

In line with the advancing technology, reliability has become one of the critical factors to be taken into consideration by the operators in the energy sector to minimize losses regarding cost and time. This issue is directly related to the reliability of the elements, namely the subsystems that make up the system. This study examines the control architecture of speed governing system within the turbine control system of hydroelectric power plants, which has to be regarded as a critical system and provides an indispensable source of guidance and knowledge to researchers and also implementation engineers as well. For this perspective, a reliability analysis has been performed for the speed governing system and the risks with the control system have been revealed. Taking IEC 61508 and IEC 61511 standards as reference within this scope, the safety concepts and the related parameters have been explained and the corresponding methods for risk analysis have been mentioned. As a result, a new safety-related control system configu-ration overcoming the unacceptable risks with the speed governing system has also been proposed. It has been proved that safety integrity level of the proposed safety-related control system is at the desired level that can make the related safety related functions verify the identified safety level
