Mitigation Technique

The contracting of a power plant construction is usually regarded as a “high risk activity”, primarily due to the lack of sufficient environmental data. Risk management has significant potential to improve the performance of the venture. Nonetheless, this requires proper and structured methods to recognize and quantify both risk factors and their interactions and, most critically, knowledge and experience. There were significantly fewer efforts to develop. The built model uses a micro-system technique to introduce a new methodology for threat assessment to define the risks associated with building power station. The methodology for evaluation enables the use of linguistic and numerical risk factor evaluations. For transform linguistic and numerical evaluations, the Fuzzy Linguistic-Numerical Conversion Scheme (FLNCS) is adopted. The predictive analysis approach often incorporates the plan pre-mitigation contingency, which is the contingency fund of threat, if no mitigation technique is introduced. A new risk management model for the development and assessment of potential mitigation strategies for each threat under consideration is established. A newly developed threat management system contrasts the current exhausted contingency with the post-mitigation contingency, tracking the effects of the chosen reduction technique. The developed risk assessment system provides an early warning that informs users that a select mitigation technique may fail. It also specifies the appropriate time to start the control cycle based on a variety of subjective criteria. Once the threat management process has begun, the control method established defines, reviews, and selects the most effective control mechanisms in favor of the selected reduction approach. If the control intervention chosen fails, the control method established notifies the client of the evaluation of the risk management program. Such alerts enable users to avoid possible future failures with similar risk objects. The built user interface has been programmed with MATLAB for easy usage.

The Way

This chapter provides an ethnography of a complex scenario involving the construction of a power plant and, in so doing, tries to show the importance of a practice-based approach to the problem of technical and organizational change. The chapter reports on fieldwork conducted in a highly complex and tightly coupled environment: power plant construction. The ethnography describes work practices on three different sites and describes and analyses their interlocking dependencies, showing the difficulties encountered at each location and the way in which the delays that result cascade through the different sites. It goes on to describe some technological solutions that are associated with augmented reality and that are being designed in response to the insights gained from the fieldwork. The chapter also reflects more generally on the relationship between fieldwork and design in real-world contexts.

This article presents a method to adjust the elements of a small wind power plant to the wind speed characterized by the highest annual level of energy. Tests were carried out on the basis of annual wind distributions at three locations. The standard range of wind speeds was reduced to that resulting from the annual wind speed distributions in these locations. The construction of the generators and the method of their excitation were adapted to the characteristics of the turbines. The results obtained for the designed power plants were compared with those obtained for a power plant with a commercial turbine adapted to a wind speed of 10 mps. The generator structure and control method were optimized using a genetic algorithm in the MATLAB program (Mathworks, Natick, MA, USA); magnetostatic calculations were carried out using the FEMM program; the simulations were conducted using a proprietary simulation program. The simulation results were verified by measurement for a switched reluctance machine of the same voltage, power, and design. Finally, the yields of the designed generators in various locations were determined.

Primary Frequency

Frequency is an important index of power quality, primary frequency regulation is of great significance for maintaining the grid frequency. In recent years, with the expansion of the power grid capacity and the continuous increase of the generator capacity, the large capacity units play a role is becoming more and more important in the primary frequency regulation of power grid. This paper takes ultra supercritical coal-fired units (1000MW) of a power plant of Hubei for example, primary frequency regulation control method, requency offset load curve and so on were studied through relevant test.
