The time spent at j on road；tmaxNot put out a fire the maximum rescue time equipped when going to rescue as fire point j；
The more fire point power grid risk matrixes of construction are designated as D,Risk Metrics D is increased
Null transformation obtains increasing null matrix E, and the increasing null transformation is included by subtracting the row least member and each by each row element
Column element subtracts the two ways that the row least member is formed and operated repeatedly until occurring N number of independent 0 yuan in matrix
Untill element, wherein, increase in row and column where 0 element independent in null matrix E refers to 0 element without other 0 elements；
All 0 elements in null matrix E will be increased and be changed into 1, all nonzero elements are changed into 0, and obtained new matrix is power network fire extinguishing
The decision matrix of equipment rescue fire point, wherein element x in decision matrixij=1 represents fire extinguishing equipment i fire fighting points j, xij=0 represents
Fire extinguishing equipment i does not remove the point j that puts out a fire.
2. more fire point power grid risk matrixes according to claim 1 increase null transformation Quick rescue method, it is characterised in that；Institute
Stating the Risk Calculation process of any circuit includes：
It is L to obtain by the circuit number that mountain fire threatens, and it is L 0/1 ordered series of numbers as power network to use random number series maker to generate length
Failure combination, represent normal operation for 1, represent to trip for 0, when having k 0 in failure combination, the failure be combined as k weights therefore
Barrier combination；
Under comprehensive stabilization of power grids margin index, power grid accident risk indicator and each failure combination of power networks risk index evaluation
Power grid risk R：

Wherein,For stabilization of power grids margin index, RaFor power grid accident risk indicator, RoFor power networks risk index；
Simulation is sampled to each heavy failure combination, in each simulation, if line tripping, the circuit is in this time simulation
Risk indicator is R；If the circuit does not trip, risk indicator of the circuit in this time simulation is 0；And
By stochastic simulation and constringent method or enumerative technique are verified, the risk indicator that any circuit is combined in each heavy failure
The risk of the respective lines finally influenceed by fiery point is converted to by weighted average.
It is quick that 3. a kind of more fire point power grid risk matrixes for being used to perform such as any methods described of claim 1 to 2 increase null transformation
Rescue system.
4. more fire point power grid risk matrixes according to claim 3 increase null transformation Quick rescue system, it is characterised in that bag
Include：
Fire point and fire extinguishing equipment information statistical module：For obtaining position and the risk information of fire point, and the position of fire extinguishing equipment
Confidence ceases；
Risk Metrics computing module：For calculating the risk Metrics of the different fire points of each fire extinguishing equipment rescue；
Risk Metrics increase null transformation module：For carrying out increasing null transformation to risk Metrics, obtain power network fire extinguishing equipment and rescue fiery point
Decision matrix, so as to obtain more fire point optimal emergency management and rescue schemes of power grid risk.
