This module is controlled in the frequency of have rendered great service of supervisory system through deploy, the further analysis that implements control target, strategy without the automation software such as result voltage control and optimize, realize the closed-loop control to electrified wire netting finally.
Realize innovation of multinomial and crucial technology
To get used to safety of electrified wire netting efficient, clean mild admits need, center of cent of adjusting control of power of group of courtyard of division of cable of China of organization of limited company of national electrified wire netting, Na Rui, area and center of provincial power adjusting control, 2017 research and development of emphasis of the nation that start plans a project " intelligence of big electrified wire netting attempers research of as crucial as safe early-warning technology and application " , new generation of research and development attempers automation system, get used to cruise in order to realize the electrified wire netting below normal operating conditions to attemper oneself, global risk is prevented in coordination accuse to deal with in coordination with complex breakdown. Among them, big below normal operating conditions electrified wire netting gets used to cruise to attemper oneself respect, the project realized multistage to attemper plan linkage carry on one's shoulder of decision-making, source cooperates with frequency of have rendered great service is decision-making and control control, automatically without result voltage wait for crucial technology innovation.
● multistage attempers plan linkage is decision-making
Multistage attempers plan linkage is decision-making it is to show one class analyses decision-making center (at present deploy moves adjusting control of center, area power to divide a center in the country) analyse decision-making center with 2 class (at present deploy is in center of provincial power adjusting control) linkage work out attempers, one class analyses decision-making center to consider entire network to run a condition, begin contact line automatically to unite optimize computation, the 2 class that optimize contact line computation to send provincial electrified wire netting as a result analyse decision-making center; The aircrew that 2 class analyse safety of give attention to two or morethings of decision-making center work out, economy, energy-saving, environmental protection exerts oneself in real time plan or bear adjust a plan. Various attemper of the plan attemper the target can be chosen attemper benefit of cost, society, energy-saving environmental protection among them one of regarding <> as simple goal, also can adopt afore-mentioned targets weight union to rise form much target to attemper.
Deviate may exist when moving actually as a result of power system the circumstance of fixed target, multistage attempers plan linkage decision making techniques is based on real time to evaluate index and demand of electrified wire netting to adjust weight, can self-correcting attempers with what adjust real time plan target, realize big electrified wire netting to get used to cruise oneself " direction is corrective " .
● source carry on one's shoulder cooperates with frequency of have rendered great service is decision-making with control
Source carry on one's shoulder cooperates with frequency of have rendered great service is decision-making interconnection electrified wire netting produces frequency or cross power of area contact line to disturb namely with control when incident, one class analyses decision-making center to apply area to control deviation function, distributing according to resource of entire network frequency modulation, frequency modulation demand and tie of tide of electrified wire netting, best frequency modulation answers formulate entire network or power is adjusted decision-making, use dynamic area to control deviation (dynamic ACE) the alternate means that waits for multistage linkage adjusts requirement quickly; Various attemper net of source of supervisory system mining carries on his shoulder or back store of all kinds attemper the frequency modulation ability of the object, develop cooperative control of frequency of have rendered great service.
