Method and device for adjusting unit comprising power supply section regions

Abstract

The invention discloses a method and device for adjusting a unit comprising power supply section regions. The method comprises the steps of: firstly obtaining a comparison section load rate of a to-be-partitioned section in actual dispatching operation, and dividing the to-be-partitioned section into a normal region, a help region, an emergency region and an out-of-limit region according to the comparison section load rate, adjusting and controlling the units in the normal region, the help region and the emergency region to obtain a unit adjusting amount corresponding to each region, and adopting an active adjusting mode to control the unit in the out-of-limit region to obtain the corresponding unit adjusting amount and the unit output in the region. According to the method, the section isdivided into the normal region, the help region, the emergency region and the out-of-limit region according to the section active power, the set section limit value, the normal region limit value andthe secondary emergency region limit value, and each region has a corresponding automatic adjustment mode, so that the workload of scheduling personnel is reduced, and the section condition judgmentaccuracy is improved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of electric power system scheduling automation, in particular to a unit adjustment method and device including power section partitions. Background technique [0002] The power system has developed into the era of large power grid interconnection and ultra-high-voltage AC-DC transmission. The system operation rules are complex. In the actual dispatching operation process of the power system, the control rules of the real-time dispatching link are generally formulated based on specific key sections to realize the control of complex power systems. "Dimensionality reduction" control of the system. The power control of key sections is the most important means to ensure the safe operation of the power grid, and the dispatching work related to it is also an important part of the real-time dispatching link. [0003] When the power system is in normal operation, the power of key sections can generally be controlled...
