Specific implementation mode
With reference to the accompanying drawings and detailed description, detailed elaboration is made to the specific embodiment of the utility model.This A little specific implementation modes only are not used for limiting the scope of the utility model or implementation principle, the guarantor of the utility model for narration Shield range is still subject to claim, including obvious changes or variations etc. made on this basis.
(1) safety stabilization control system structure
Electricity net safety stable controlling system mainly by control main website, control sub-station, cut machine/cutting load and execute station and form, Control function at present mainly based on controlling on the spot, related data from picking up from uses, therefore inevitably there are data acquisition, lead to T unit etc. repeats allocation problem.For this purpose, establishing one as shown in Figure 1 on conventional security stabilizing control system architecture basics Change layered cooperative structure.The structure mainly controls the three of main website by establishing net grade control main website, provincial control main website and city-level Grade control hierarchy structure, and realize that sharing functionality is transmitted in electrical data acquisition and information with communication interface by data acquisition.
Net grade control main website divides into multiple provincial control main websites, and provincial control main website includes multiple city-level controls main website.City Grade control main website divides into multiple control sub-stations, and control main website is issued to each control sub-station with communication interface by data acquisition and cut Machine, cutting load order, by cutting machine, cutting load execution station completes to cut machine, cutting load function.Wherein, control sub-station and cut machine, cut it is negative Lotus executes station and is all made of duplicate system retrofit guarantee reliability.Meanwhile the control main website of different levels also can according to passway for transmitting electricity and The actual conditions down set portion control sub-station of power supply and cut machine accordingly, cutting load executes station, realization the trans-regional interconnection in part Security and stability control under the catastrophe failure of road.
Each main station system will cut machine accordingly according to the fault message monitored, cutting load instruction is issued to subordinate control master It stands, information is issued to control sub-station by control main website by data acquisition with communication interface, is issued to order accordingly by it Substation (execute substation and be deployed in power plant and load point) is executed, will finally cut machine, cutting load amount decomposes to control sub-station simultaneously step by step Machine of specifically cutting, cutting load operation are realized by executing substation.In addition, each control sub-station believes the power information of acquisition, circuit Breath etc. is transmitted to data acquisition and is stored and forwarded with message center.
(2) information interactive interface
As shown in Fig. 2 information interactive interfaces, following information exchange function can be realized with communication interface by data acquisition, Include mainly that equipment access, information monitoring and order issue:
1) data acquisition control has protocol conversion function with communication interface, adapts to Unified Communication stipulations and is based on " E lattice It is sent on the safety control information of formula " and the access of different manufacturers and different model security control device.
2) electric quantity informations such as monitoring device operating status and channel status, fault message, line voltage distribution and electric current, element Throwing stops and can cut status information, the current method of operation, pressing plate state and throws bounce breath, device exception and warning information, action report Accuse the information such as (including action element and action message) and recorder data, definite value and off-line strategy
3) information inquiry and calling, the modification command informations such as definite value issue.
(3) trans-regional Collaborative Control
Upper wire grade, which controls main website and control main website of provinces and cities of lower layer, control sub-station and executes station, can carry out electrical data The interaction of the information such as information and control command controls main website and control sub-station and is realized differently with communication interface by data acquisition Area's gathered data is shared.
Top level control main website can acquire the output level etc. for obtaining fault message, the load level of each load point, power supply point Various data informations can be optimized based on the different regions data information of top level control main website acquisition and be planned as a whole local and across ground Area controls resource, realizes such as variety classes power supply, load flexible trans-regional resource allocation on a large scale, and across differently pacifying The Collaborative Control of control measure, such as there are conflicting risks for the measure of different regions DC control for reduction.
(4) Emergency Control Strategy
When executing cutting load operation, mainly according to the load significance level, the cutting load frequency and load value of different load point Size determines load excision strategy.
1) load point is ranked up according to load important level, it is preferential to cut off three low stage loads of importance.First to three The frequency of cutting load of stage load point is ranked up, the preferential load for cutting off the less load point of the cutting load frequency.Meanwhile comparing The load value size of the cutting load amount and load point assigned, and the larger load point of selection load as possible.
2) when three-level load value is unsatisfactory for the cutting load amount assigned, consider two stage load of cut-out, and Integrated comparative The frequency of cutting load and load value of load point, the preferential excision less larger load point of load and load value of the cutting load frequency Sub-load.
