Description
Technical field:
The present invention relates to a kind of power transmission and transformation fields, more particularly to a kind of for increasing the side of electric power responsible consumer electricity consumption reliability
Method and device.
Background technique:
Requirement with the increasing important power consumers of the development of social economy to power supply reliability is higher and higher, and regional
Administrative and dual power supply user mostly joint uses route and relaying configuration level is fairly simple, when permanent fault occurs for route
It will cause power loss all the way, it is therefore necessary to improve the power supply reliability of important power consumers.
Influence responsible consumer power supply reliability external factor mainly have: the restriction of enterprise external environment i.e. urban construction and
The restriction that external force is destroyed；It is frequent that the restriction of user, that is, user's industry expands engineering, and only so that basic routing line is had a power failure the expansion of single industry, shows
Amount when so losing many.
The main internal factor for having a power failure and restricting power supply reliability raising has, and mainly there are two aspects for safety at power cut: pre- peace
Row has a power failure and fault outage.By taking power grid as an example, pre-arranged power failure probably accounts for 87%, and fault outage only accounts for 13%.
Restriction in terms of rack: line looped network rate, segments, the restriction of big separated time number of users；The restriction of device standard；
Restriction in terms of thought and knowledge: the reliable sex consciousness of base line worker is relatively thin weak, and in fact reliability management class runs through
In production overall process, total involvement is needed；
Manage network to restrict: administrative staff are insufficient, update drawing and data not in time, not can guarantee the timeliness of data and accurate
Property；
Examine the restriction of system: reliability index only examines distribution, and all units of influence reliability factor are not included in and are examined
Core；
In short, electric power responsible consumer power supply reliability, is an important content of management of electric power dependability, power distribution system is directly embodied
The power supply capacity united to user, reflects power industry to the satisfaction degree of national economy electrical energy demands.
Summary of the invention:
The technical problems to be solved by the present invention are: overcoming the deficiencies of the prior art and provide a kind of to important subscribers' line installation
Interconnection switch mitigates responsible consumer by responsible consumer line load down to another route by the Loop Closing Operation of interconnection switch
The method for being used to increase electric power responsible consumer electricity consumption reliability of the load pressure of route.
The technical scheme is that a kind of for increasing the side of electric power responsible consumer electricity consumption reliability in two lines road
Method, when responsible consumer line load is larger, passes through the conjunction of interconnection switch in responsible consumer with interconnection switch is installed in electric line additional
Ring operation mitigates the load pressure of responsible consumer route, the steps include: by responsible consumer line load down to another route
Step 1: analysis two lines road level power supply point be ground adjust license can Loop Closing Operation power supply point, and judge whether full
Sufficient two lines road carries out a possibility that Loop Closing Operation；
Step 2: transferring two lines road load curve over the years, and analyze two lines road year maximum current value and average annual current value；
Step 3: transferring the protection definite value parameter on two lines road；
Step 4: installing interconnection switch at a distance of nearest or crossover location on two lines road according to the trend on two lines road；
Step 5: when responsible consumer line load is larger, by the Loop Closing Operation of interconnection switch, by responsible consumer line load
Down to another route, mitigate the load pressure of responsible consumer route.
Further, the protection definite value parameter is that current transformer ratio parameter and route can be with maximum current values.
Further, the model FZW-32 of the interconnection switch uses single lever-type manual operation, electric operating or remote
Control operation.
It is a kind of for increasing the device of electric power responsible consumer electricity consumption reliability in two lines road, including a responsible consumer line
Road and an insignificant subscribers' line, it is characterized in that: interconnection switch is installed between two lines road, electricity manual by single lever-type
The interconnection switch is moved or far controlled, realizes the Loop Closing Operation on two lines road.
Further, the distance of two routes is arranged in the model FZW-32 of the interconnection switch, the interconnection switch
Relatively close or crossover location.
The beneficial effects of the present invention are:
1, the present invention installs interconnection switch additional to important subscribers' line, by the Loop Closing Operation of interconnection switch, by responsible consumer route
Load mitigates the load pressure of responsible consumer route down to another route, while in a route when switch maintenance, can incite somebody to action
Load transfer reduces scope of power outage, improves power supply reliability.
2, the present invention greatly reduces pre-arranged power off time, and the schedule ahead responsible consumer method of operation carries out load transfer.
3, present invention optimization Distributing network structure, the looped network rate for improving route improve the general level of the health of route, switch
It is easy to operate, quick, realize the fast transfer of load.
Specific embodiment:
Embodiment:
For increasing the method and device of electric power responsible consumer electricity consumption reliability in two lines road, in responsible consumer electric line
Interconnection switch is installed additional, by the Loop Closing Operation of interconnection switch, responsible consumer route to be born when responsible consumer line load is larger
Lotus mitigates the load pressure of responsible consumer route, the steps include: down to another route
Step 1: analysis two lines road level power supply point be ground adjust license can Loop Closing Operation power supply point, and judge whether full
Sufficient two lines road carries out a possibility that Loop Closing Operation；
Step 2: transferring two lines road load curve over the years, and analyze two lines road year maximum current value and average annual current value；
Step 3: transferring the protection definite value parameter on two lines road；
Step 4: installing interconnection switch at a distance of nearest or crossover location on two lines road according to the trend on two lines road；
Step 5: when responsible consumer line load is larger, by the Loop Closing Operation of interconnection switch, by responsible consumer line load
Down to another route, mitigate the load pressure of responsible consumer route.
Further, protection definite value parameter is that current transformer ratio parameter and route can be with maximum current values.
Further, the model FZW-32 of interconnection switch uses single lever-type manual operation, electric operating or remote control behaviour
Make.
