Power automatic adjusting method and system of low-voltage excess pressure and excess heat power generating set

Abstract

The invention discloses a power automatic adjusting method and system of a low-voltage excess pressure and excess heat power generating set. The power automatic adjusting method comprises the following steps that current condition monitoring signals are acquired; the power mode of the power generating set is determined according to the acquired current condition monitoring signals, the power generating set is controlled to enter in the determined power mode, the active power and reactive power of the power generating set are adjusted to preset setting values under the determined power mode, and the power generating set is made to work under the power mode. The power automatic adjusting system of the low-voltage excess pressure and excess heat power generating set integrates a measuring module, an automatic control module and the like, improves the equipment integration degree, reduces faults caused by system connection, and lowers maintenance cost. The power automatic adjusting methodand system are particularly suitable for excess pressure and excess heat power generating sets of small and medium-sized enterprises. Automatic control over the power of the power generating set is achieved, the technological dependence on on-site working personnel and later maintenance personnel is reduced, and the automation and intelligence level of equipment operation is improved.

Description

technical field [0001] The invention relates to the field of intelligent control of electric power equipment, in particular to a method and system for automatically adjusting the power of a low-voltage residual pressure and residual heat 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.
