Variable Pressure Peaking Boiler, Operation, Testing, and Control

During the last few years many utilities have been purchasing fossil fueled power plants designed to be used for initial or future cycling service. As more large nuclear units are placed in service with their low incremental operating cost, it is anticipated that many fossil units will be operated to meet daily cycling load demands while still retaining the ability to efficiently supply a large amount of the system base load, if it is required. This paper discusses the operation and control of a gas and oil fired variable pressure drum boiler specified and designed for peaking operation at a major U. S. utility company. Operating results obtained during normal unit shutdowns, startups for morning peak load, and rapid, variable, and constant pressure load changes are presented. Also discussed are the major control system features employed for variable pressure operation as well as operation of the superheater by-pass system. The advantages of variable pressure operation are pointed out and explained along with supporting operational data.

The demand for electricity is increasing day by day due to technological advancements. According to the demand, the size of the grid is also increasing rapidly in the past decade. However, the traditional centralized power grid has many drawbacks such as high operating cost, customer satisfaction, less reliability, and security. Distribution generation has less pollution, high energy efficiency, and flexible installation than traditional generation. It also improves the performance of the grid in peak load and reliability of supply. The concept of micro-grid has been raised due to the advent of new technologies and development of the power electronics and modern control theory. Micro-grid is the significant part of the distribution network in the future of smart grid, which has advanced and flexible operation and control pattern, and integrates distributed clean energy.

And Control

As the four-wheel steering (4WS) system has great potentials, many researchers' attention was attracted to this technique and active research was made. As a result, passenger cars equipped with 4WS systems were put on the market a few years ago. This report tries to identify the essential elements of the 4WS technology in terms of vehicle dynamics and control techniques. Based on the findings of this investigation, the report gives a mechanism of electronically controlling the steering system depending on the variable pressure applied on it. This enhances the controlling and smoothens the operation of steering mechanism.
