Abstract
The invention discloses an automatic switch method for a standby power source with a small power source grid-connected system. The automatic switch method for the standby power source is characterized in that two modes, namely a mode that a bus coupler or a bridge switch is utilized for switching a small power source automatically and a mode that incoming lines are utilized for switching the small power source automatically, are utilized. The automatic switch method for the standby power source with the small power source grid-connected system has the advantages that the rate that the small power source is switched by mistake is greatly lowered, the operation reliability of a power grid, especially the operation reliability of a small power supply unit is improved, and the automatic switch method for the standby power source with the small power source grid-connected system can also be applied and popularized in other protection enterprises.
Description
Technical field
The present invention relates to the electric power project engineering field, relate in particular to a kind of automatic closing control method with the small power incorporating into power network system.
Background technology
Along with the increasingly raising of user to the power supply reliability requirement, the plurality of advantages such as automatic switching device of standby power supply is simple with its principle, realization is convenient, investment is little, reliable in action, be widely used in modern power network, but same because the simple reason of its principle, when the primary connection low-pressure side that prepared auto restart installation site in electric substation occurred is linked with the small power incorporating into power network circuit, present prepared auto restart design principle is all too oversimplified on processing, and has so also caused the appearance of the meaningless solution net of many small generation sets problem.Along with the access of the power generation projects such as environmental protection thermoelectricity project, Wind Power Project and some novel energies starts, after original standby throwing mode exists prepared auto restart action jumping working power switch, with the risk of small power supply asynchronous parallelizing, need to carry out the corresponding demand that could adapt to electrical network of adjusting when closing Backup Power Switch.Conventional prepared auto restart connection is jumped the existing problem of principle: do not sentence the physical location of small power supply switch, exist mistake to cut the be incorporated into the power networks situation of small power supply of non-fault line, the situation that exists mistake to cut the small power incorporating into power network circuit under charged state.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in prior art.
Summary of the invention
The purpose of this invention is to provide a kind of automatic closing control method with the small power incorporating into power network system.
The technical solution used in the present invention is:
automatic closing control method with the small power incorporating into power network system, it is characterized in that: the standby band small power supply mode of throwing of mother or bridge switch: after charging is completed, through time-delay, if satisfy bus (I) with no pressure, inlet wire (1#) is without stream, tripping disconnect (1DL) after delaying time, when connection is cut bus (I) small power supply control word (KG2.8) for dropping into, when bus (I) small power supply has stream to differentiate (KG2.11) for input, after the small power supply of bus (I) has stream, tripping disconnect (1DL) joins simultaneously jumps bus (I) small power supply, confirm that disconnect (1DL) and the equal tripping of bus (I) small power supply are by the time-delay disconnect (2DL) that closes, if do not satisfy, return.
automatic closing control method with the small power incorporating into power network system, it is characterized in that: the standby band small power supply mode of throwing of inlet wire: after charging is completed, through time-delay, if satisfy bus (I), bus (II) is with no pressure all, and inlet wire (1#) is without stream, inlet wire (2#) has that to press be that small power supply has stream to differentiate (KG2.0) when dropping into, tripping disconnect (1DL) after time-delay, confirm disconnect (1DL) tripping, the small power supply switch is in jumps the position, inlet wire (2#) has that to press be that small power supply has stream to differentiate (KG2.0) when dropping into, through time-delay make and break way switch (2DL), if do not satisfy, return, when connection cut bus (I) small power supply control word (KG2.8) for drop into, bus (I) small power supply has stream to differentiate (KG2.11) when dropping into, after the small power supply of bus (I) had stream, tripping disconnect (1DL) join jumping bus (I) small power supply simultaneously, when connection cut bus (II) small power supply control word (KG2.9) for drop into, bus (II) small power supply has stream to differentiate (KG2.12) when dropping into, after the small power supply of bus (II) had stream, tripping disconnect (1DL) join jumping bus (II) small power supply simultaneously.
Advantage of the present invention is: greatly reduce the probability that small power supply mistake is cut, improve the operational reliability, the particularly operational reliability of small power supply unit of electrical network, also can carry out application in other protection enterprise.
Description of drawings
