Research and Application of Voltage Reactive Control Deviation Indicators QCE
The voltage control mode presently used for voltage monitoring is not strict enough to reflect the current voltage level comprehensively,especially unable to provide a reasonable control method as for the unqualified voltage indicator.Based on the grid real-time voltage and reactive data collection,this paper presents the reactive control deviation QCE for relation-type voltage control indicators,in order to cover the deficiencies and defects of the existing target-type voltage control indicators,and change the traditional voltage index calculation and management.It proves helpful for dispatchers to master the grid voltage level and make quick and correct judgment and adjustment according to the indicator prompts,providing intelligent decision support as an important means to safeguard network security and emergency operation.
