Low voltage waste heat overbottom pressure generator set control system

Abstract

The invention discloses a low voltage waste heat overbottom pressure generator set control system. The low voltage waste heat overbottom pressure generator set control system comprises a measuring module used for collecting analog quantity and switching state quantity relating to a generator set, a protection module used for achieving instantaneous overcurrent protection, overcurrent protection, overload protection, voltage abnormality protection, frequency abnormality protection and overspeed protection, a control module used for sending control commands to the modules to achieve generator set operation control, a simultaneous grid connection module used for achieving simultaneous grid connection of the generator set, a communication module used for achieving communication among the modules and communication with equipment outside the system. The control module communicates with other modules through the communication module respectively. The functions of measurement, protection, automatic control, simultaneous grid connection and the like are centralized into the control unit, and therefore equipment integration level is improved, connecting cables are reduced, the cost is lowered, faults caused by subsystem connection are reduced, and the maintenance cost is lowered.

Description

technical field [0001] The invention relates to the field of intelligent control of electric equipment, in particular to a control system of a low-voltage waste heat and waste pressure generating set. Background technique [0002] The use of waste heat and pressure is an important measure for energy-saving and emission reduction in high-energy-consuming enterprises, but at present, it is mainly used by large-scale high-energy-consuming enterprises, and it has not been fully utilized in many small and medium-sized enterprises. In the process of waste pressure utilization, the production methods, production processes, production equipment, raw materials and environmental conditions used are different, which brings many difficulties to the utilization of waste heat and pressure. As the concept of low-carbon and environmental protection becomes more and more popular, the utilization of waste heat and pressure It has received the attention of the country and enterprises, and ther...
