For the ease of more fully understanding the determination method of the above-mentioned power supply reliability of the application, implement below in conjunction with specific
Mode carries out detailed exemplary description to this method.
1, first, group of networks is divided：For a certain power supply area, group of networks division is carried out to the power supply area,
And obtain the number of supply network group all in the region, that is, collect the number of supply network group all in the region and standby
With.The determination method of network group model is by taking dual-ring network system shown in Fig. 2 as an example, detailed description.
It is scanned since the 10kV busbares 1 of substation or Switching Station, by breaker 1, scans, deposit along supply path
In the case of branch (branch of powering where such as figure load point E, F, G), the distribution for searching the end of each branch is needed
Facility, and store all scanned equipment and device attribute.Search load point A always along supply path, the load point institute
Distribution facility in all devices also belong to a group of networks, therefore upwards to 10kV busbares 2 since load point B points
All devices also belong to the group of networks；During search, the equipment with function is cut-off is encountered, it is assumed that with cut-offfing
The equipment of function is in the conduction state, continues search for, and therefore, may search for from A points to C points and finds 10kV busbares 3, from B points
It may search for D points and arrive 10kV busbares 4, thus complete the scanning of whole network group as shown in Figure 2, met in scanning process
To all devices be required for storing.
It is similar with above-mentioned steps, it needs to complete to scan for the rack of Beijing area, determines all network group models, and
And each network group model is required for being identified, i.e., each group of networks has unique number, later if rack is constant,
Network group model is constant；If rack changes, the equipment inside corresponding network group model increases and decreases work.
During storage, the attribute of storage device is needed, wherein device attribute includes：Area, equipment belonging to equipment
Whether whether connection type have accident indicator, be with the following functions：Remote signalling, remote control, remote sensing, equipment connection mode packet
It includes：It is to be connected by aerial cable or connected by power cable.
2, secondly, based on above-mentioned group of networks analysis power grid normal operating mode and failure operation mode：By the first model
Simplified, as Fig. 3 and Fig. 4 is indicated, wherein D1, D2 ... D10 in Fig. 3 and Fig. 4 indicate tie point 1, tie point respectively
2 ... tie points 10 retain to have and cut-off the equipment of function by taking Fig. 3 as an example, for example, breaker and on-load switch etc. can open or
The equipment of shutdown retains the equipment of all adjustable power system operating modes, and other equipment of all are all reduced to a point,
The connection relation of breaker and on-load switch has thus been obtained, but has needed attribute (the affiliated substation of clear breaker
Or Switching Station) and on-load switch attribute (distribution facility of subordinate).Defining each has the both ends for the equipment for cut-offfing function,
Respectively a, b point, can thus obtain the connection relation of each equipment, in this way the attribute at each equipment both ends just only there are two types of
Attribute：It is located at the point of end in connection end point or network group model for connecting device node.The model finally obtained is such as
Shown in Fig. 4：Each switchgear with both ends attribute only need to be reduced to.
According to network group model, the normal operating mode of power grid is obtained using matrix algorithm, that is, has and cut-offs setting for function
Standby state.
According to network group model, in addition to the normal operating mode of power grid to be returned, it is also necessary to feed back the operation side after failure
Formula：It is specific to consider that principle is one point of each failure (having the equipment fault for cut-offfing function or connection point failure), to the greatest extent may be used
It can guarantee tie point not dead electricity, provide the method for operation after the minimum fault recovery of all switch motions.Such as：1 failure of equipment
In the case of, it needs to close equipment 7；If the connection point failure between equipment 1 and equipment 6, needs off device 1, equipment
6, equipment 7 is closed.
3, then, temporal information is calculated based on the method for operation after fault recovery, i.e., is born caused by each equipment fault
Lotus point power off time：Power off time caused by the equipment of analyzing influence each load point power supply, by taking A points as an example, in addition to divide
The power off time after each equipment fault of its present situation power supply branch road is analysed, it is also contemplated that the load point E of the protection of breaker 1,
F, power off time caused by the branch equipment failure where G.If determining for power off time needs consideration can be by least moving
Make carry out fault recovery, then power off time is the back brake switching time of switch, and otherwise power off time is the repair time of equipment.
4, last, determine power supply reliability index：Need to find out the year power off time t of each load pointN, tNIt is negative equal to this
The summation of power off time caused by the failure rate of all association power supply units of lotus point is multiplied by the equipment, by taking A points as an example, power supply
Reliability index is：tAIt is to have 8760 hours by 1 year for the year power off time of load point A, 8760.
For the group of networks α being made of load point A, B, C, it is assumed that the capacity of distribution transform of A point bands is PA, B point bands match transfiguration
Amount is PB, the capacity of distribution transform of C point bands is PC, then the reliability index of whole network group α be：For by group of networks α, network
The system of group β, group of networks γ compositions, it is assumed that the capacity of distribution transform of α bands is Pα, the capacity of distribution transform of β bands is PBeta, gammaThe capacity of distribution transform of band is
Pγ, the power supply reliability index of the system is：
The method of operation using the actual operating for obtaining power grid by group of networks and after breaking down, and calculate reality
Caused by the fault outage time, the fault outage time obtained by method in the embodiment of the present application relatively connects with actual conditions
Closely, the power supply reliability precision obtained is higher.
