Embodiment Construction

[0035] The power system adequacy evaluation system of the present invention, such as figure 1 As shown, according to different evaluation objects, it includes three parts: generation capacity adequacy evaluation module, network power supply vulnerability evaluation module and system unit adequacy evaluation module, and the three modules carry out corresponding evaluation independently.

[0036] Generation capacity adequacy refers to the ability of generating equipment to continuously provide sufficient power and electricity demand to users, and to maintain this ability during peak loads and expected and moderately unexpected failures of generating equipment. The vulnerability of network power supply refers to the ability of the system to withstand interference or failure under the normal operation of the system or various random factors, and the possible trend and impact of the system not being able to maintain normal operation.

[0037] Both the assessment of generation capac...

Abstract

The invention discloses a system for evaluating adequacy of a power supply system, comprising a generating capacity adequacy evaluating module, a network power supply vulnerability evaluating module and a system unit adequacy evaluating module, wherein the system unit adequacy module specifically comprises a unit power supply capacity adequacy evaluating module, a unit power transmission capacity adequacy evaluating module and a power transmission cross section / channel power transmission capacity adequacy evaluating module. System running personnel can select a certainty criterion or a probability risk criterion as an adequacy evaluating standard according to actual requirements. By adopting the system disclosed by the invention, content and indexes of power supply system adequacy evaluation are enriched, evaluation feasibility and effectiveness can be improved, scientific evidence can be provided for system running planning, and a weak link which exists in the power supply system can be identified.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a power system adequacy evaluation system. Background technique [0002] Adequacy is one of the key indicators to describe the reliability and economy of the power system, which can be simply explained as "how far from the basic state to the predetermined direction to reach the dangerous area". With the continuous expansion of the power system scale and the increasingly complex operating characteristics, some existing simple and easy manual calculation of adequacy indicators have become increasingly difficult to meet the actual needs of modern power system planning and operation. Contents of the invention [0003] Aiming at the above problems, the present invention develops a set of power system adequacy evaluation system, which enriches the indicators of adequacy evaluation and improves the accuracy and credibility of adequacy evaluation. [0004] The power system adequ...
