Abstract

The invention discloses a method and a system for cooperatively evaluating the reliability of a power transmission and transformation system and a power distribution system based on partition simplification. The method comprises the following steps: partitioning a power distribution system into partitioning power supply areas according to a switch device, and partitioning the power supply area by using the switch as a boundary; partitioning into circuit partitions according to a component group of the power transmission and transformation system, and partitioning the power transmission and transformation system; traversing component failures of the power transmission and transformation system; traversing failures of internal components of a transformer substation; traversing component failures of a middle-voltage power transmission system; and acquiring the reliability index of the power transmission and transformation system and the power distribution system according to the component failures of the power transmission and transformation system, the failures of the internal components of the transformer substation and the component failures of the middle-voltage power transmission system. Through the scheme, the whole power supply reliability level of the power transmission and transformation system is balanced, so that scientific and reasonable construction of the power transmission and transformation system and the power distribution system is guided, and the development of reliable operation and maintenance of the power transmission and transformation system and the power distribution system is guided.

Description

technical field [0001] The present invention relates to the technical field of power system reliability evaluation, and more specifically, relates to a method and system for collaborative evaluation of power transmission and transformation and power distribution system reliability based on partition simplification. Background technique [0002] With the continuous growth and maturity of the power system scale, the study of power system reliability has become one of the most important research objects of the power system. Due to the huge scale and complex structure of the power system, the system is also divided into several subsystems in terms of system reliability research, such as: power generation system, power transmission and transformation system, and power distribution system. Each subsystem can be evaluated separately according to the functional characteristics of these subsystems. reliability. my country's current "Reliability Evaluation Procedures for Power Transm...
