Document Type and Number:
WIPO Patent Application WO/2017/071548
Kind Code:
A1
Abstract:
A balance control method and system for abrupt change in device output. The method comprises: acquiring device output information containing a rated device output, a current device output, a set adjusted amount and a measured adjusted amount, and obtaining a device output override control condition (S101); detecting a device output override decrease condition and override increase condition (S102); and if the override increase condition is detected, increasing a device control instruction according to a predetermined rate, and if the override decrease condition is detected, decreasing a device control instruction according to a predetermined rate (S103). By means of the method, non-linear characteristics of a device control instruction and a device output are overcome, and a machine set can rapidly reach a safe and stable new operating condition.
