Embodiment Construction

[0030] Such as Figure 1-2 As shown, a logic framework-based grid power supply reliability planning method described in an embodiment of the present invention includes the following steps:

[0031] Step 1: Set the initial value and calculate the reliability index of the initial plan. If the set initial value is reached, the overall investment will be counted. If the overall investment does not exceed the investment budget, the plan will be given; if the overall investment exceeds the investment budget, Then modify the reliability target, and re-calculate the overall investment to the load investment budget, and then give the plan;

[0032] The reliability target calculation in the step 1 includes the following steps:

[0033] Step 1.1: Obtain the network parameters, operating parameters, equipment parameters and management parameters of the distribution network to be evaluated;

[0034] Step 1.2: According to each parameter obtained in step 1.1, determine the failure probabi...

Abstract

The invention relates to a planning method of power grid power supply reliability based on a logic frame, which comprises the following steps: setting initial value, calculating reliability index of an initial scheme, conducting statistics on integral investment and giving a plan scheme if the index achieves the set initial value, sequentially determining whether the management parameter has improvement space or not, whether the number of users on each section is larger than 8 or not, whether feeder load factor is larger than 40% or not, whether the ring networking rate is larger than 100% or not, whether the proportion of failure power failure in the overall users reaches 50% or not, whether users without protection exists or not, whether a planning target is smaller than 2 hours or not and whether equipment fault rate is higher than national average value that the target corresponds to or not if the reliability index of the initial scheme does no reach the set initial value, determining again whether the planning target is smaller than 2 hours or not and finally giving the plan scheme. The planning method has the advantages of filling the blank of power distribution reliability of the national power grid, being strict in logic, complete in system and standardized and being suitable for power supply enterprises.

Description

technical field [0001] The invention relates to a grid power supply reliability planning method based on a logical framework. Background technique [0002] In today's society, electricity, like air and water, has become a necessity for people's life. With the development of the economy and the continuous improvement of people's living standards, the society has higher and higher requirements for the reliability of power grid power supply. Therefore, power supply enterprises have always regarded improving the reliability level of the power grid as the top priority of their work, and regard reliability planning as the leader of reliability technology and management. [0003] Power supply reliability runs through the main business departments of power supply enterprises and is closely related to the power grid. When compiling power supply reliability planning, it is necessary to coordinate different goals, different departments, formulate different schemes, and compare and op...
