Debugging method of heat-engine plant field bus

Abstract

The invention belongs to the technical field of automatic control of heat-engine plant set, and specifically relates to a debugging method of a heat-engine plant field bus. The debugging method of a heat-engine plant field bus includes type selection and application range of the field bus, the key points and important matters needing attention during the construction process of the field bus, andthe technical points of configuration and debugging of the field bus. The debugging method of a heat-engine plant field bus preferably applies the bus technology to automatic control of the heat-engine plant, is simple, reliable, economical and practical, can fully improve the intelligent control and automation level of the whole heat-engine plant, can save the energy and is environmentally friendly at the same time, and can save the mounting cost and the maintenance cost, thus being economical and practical. Besides, the debugging method of a heat-engine plant field bus can guarantee reliableand stable operation of equipment or system, and at the same time the bus technology can realize bidirectional serial multinode digital communication, can provide more flexible system integration initiative, can also improve the adaptability of the system to the field environment, thus providing a new direction for automatic control of the heat-engine plant.

Description

technical field [0001] The invention belongs to the technical field of automatic control of thermal power plant units, and in particular relates to a debugging method for a thermal power plant field bus. Background technique [0002] The function dispersion of traditional DCS controllers in thermal power plants is not very effective in reducing the cost of control engineering in practical applications. With the improvement of automation level, the functions of DCS controllers are also continuously improved, and the physical dispersion of control systems is also constantly From the remote I / O, remote control station, power cabinet and power distribution cabinet commonly used in power plants, the intelligent acquisition front-end is installed in the power plant, but usually the distribution of electronic devices is very scattered and the distance is large, only the use of fieldbus Technology is the key to reducing the operating economy of thermal power plants; at the same time...

[0002] The function dispersion of traditional DCS controllers in thermal power plants is not very effective in reducing the cost of control engineering in practical applications. With the improvement of automation level, the functions of DCS controllers are also continuously improved, and the physical dispersion of control systems is also constantly From the remote I / O, remote control station, power cabinet and power distribution cabinet commonly used in power plants, the intelligent acquisition front-end is installed in the power plant, but usually the distribution of electronic devices is very scattered and the distance is large, only the use of fieldbus Technology is the key to reducing the operating economy of thermal power plants; at the same time, the traditional DCS is used, the system communication network ends at the control station or input and output unit, and the field instruments or equipment still use one-to-one digital or analog signal transmission, which is wasteful raw materials, and cannot fully guarantee the reliability of the signal
