Abstract
The invention discloses a kind of dereliction formula bus protection implementation methods on the spot; each interval protection handset is all made of respective site protective device; realize the distributed bus differential protection based on bidirectional loop network; electric current, voltage analog and the switching value of this side of each interval protection handset in-site collecting, and pass through dual-ring network and other protection handset two-way communication shared datas；Each interval protection handset realizes each interval autoprotection function; such as route protection handset realizes the route protection equation of light, distance, overcurrent defencive function; interval protection handset is according to autoprotection protection act condition and female poor differential protection operation condition, the corresponding breaker of tripping.The present invention regards bus protection handset using the protection of each interval site, and each analog quantity and switching value for being spaced site protection and only acquiring this side, by dual-ring network shared data, therefore handset is small, can install on the spot, and reduces original busbar protective device.
Description
Technical field
The present invention relates to Relay Protection Technology in Power System fields, and in particular to a kind of realization of dereliction formula bus protection on the spot
Method.
Background technology
Current each substation is divided into conventional substation and intelligent substation.The protective device of conventional substation is installed on protection
It in control room, is switched far from primary equipment, results in the need for being attached using a large amount of cable, investment is larger.Intelligent substation
Using the system architecture of " three layer of two net ", the equipment such as combining unit, intelligent terminal are installed near primary equipment, protective device peace
Loaded in protection control room, a large amount of optical cable is thereby produced, and produce some new problems, such as protection sampling, tripping
Link increases, rapidity and reliability decrease；The network architecture is complicated, and interchanger quantity is more.
In addition, traditional centralized bus protection causes body since it will acquire the analog quantity of each side and switching value data
Product is big, such as using installing on the spot, cable distance can be caused longer, and device quantity is more.
Invention content
In view of the above problems, the present invention proposes a kind of guarantor protecting simultaneous bus protection handset function based on circuit site
Maintaining method.
In order to achieve the above objectives, the invention is realized by the following technical scheme：
A kind of dereliction site bus differential protection device based on dual-ring network, by route protection handset, main transformer protection handset, mother
UNPROFOR protects handset, sectionalised protection handset is constituted, busbar voltage handset, and be respectively spaced oneself and it is respective build protection, simultaneously
Each interval handset is connected by hand-in-hand dual-ring network, each magnitude of current for being spaced this interval of handset in-site collecting, voltage and its
Switching value needed for this interval, and by hand-in-hand dual-ring network and other handset shared datas, finally realize each interval protection
Function and bus protection function.
The implementation method of each interval voltage acquisition is：When busbar is applied to double-bus situation, each interval protection handset
Required voltage shares to the protection of other intervals by busbar voltage handset by dual-ring network of handing in hand, what each interval was acquired by cable
Disconnecting link position carries out voltage switching selection and uses mother's I voltage or mother's II voltage, and realizes its interval autoprotection function.
Respectively the method for interval protection handset realization bus protection function is：Voltage, electric current, knife needed for each interval protection handset
Gate position shares to the protection of other intervals by each interval handset by dual-ring network of handing in hand, and realizes that each interval protection handset is differential
The calculating of protection is to select to realize bus protection function, and by each corresponding breaker tripping of protection handset.
Beneficial effects of the present invention：
The dereliction formula site busbar protective device based on dual-ring network of the present invention and guard method, on the spot using each interval
Change protection and regard bus protection handset, each analog quantity and switching value for being spaced site protection and only acquiring this side passes through dual-ring network
Shared data, therefore handset is small, can install on the spot, and reduce original busbar protective device.
Description of the drawings
Fig. 1 is that a kind of topology of embodiment of the dereliction formula site busbar protective device based on dual-ring network of the present invention is shown
It is intended to.
Fig. 2 is a kind of a kind of embodiment of guard method using dereliction formula site busbar protective device of the present invention
Flow diagram.
Specific implementation mode
Below with reference to attached drawing, the guard method of the dereliction formula site busbar protective device of the present invention is carried out specifically
It is bright.
As depicted in figs. 1 and 2, a kind of dereliction formula busbar protective device on the spot, including more route protection handsets, more masters
Become protection handset, mother protection handset, sectionalised protection handset, busbar voltage handset, each protection handset passes through hand-in-hand bicyclic
Net is attached, each electric current, voltage analog and busbar chopper switch amount for protecting handset in-site collecting itself, each to realize
Protection interval autoprotection is (i.e.：Route protection handset realizes that route protection function, main transformer protection handset realize main transformer protection work(
Energy, mother protection handset realize that mother defencive function, sectionalised protection handset realize that sectionalised protection function, busbar voltage handset are realized
Busbar voltage acquires), and protected to other intervals by hand-in-hand dual-ring network and oneself carry out data sharing, to each interval
Protection handset realizes that female poor differential protection calculates, and every interval protection handset includes female poor all defencive functions, and root
Itself breaker is jumped according to female poor the result of the action, hair trip protection order is protected to other intervals by dual-ring network.
