Abstract

The invention provides an on-line state evaluation method for a secondary system of an intelligent substation. The secondary system comprises a secondary network and secondary equipment. The method comprises the following steps of monitoring on-line states of the secondary equipment; collecting the on-line states of the secondary equipment and on-line states of the secondary network to an object database; and evaluating the on-line states of the secondary system. The on-line state evaluation method has the advantages that the risk of false judgment caused by experience difference between different persons is reduced, the troubleshooting time is shortened, the non-planned outage time and the overhauling outage time of the intelligent substation are reduced, and the on-site overhauling workload is saved.

Description

technical field [0001] The invention belongs to the technical field of automation, and in particular relates to an online state evaluation method of a secondary system of an intelligent substation. Background technique [0002] In traditional substations, detailed testing, monitoring, and operation and maintenance management specifications for secondary equipment have been established to form a complete system, effectively ensuring the normal implementation of secondary functions and ensuring the safe and stable operation of the power grid. Compared with the traditional substation, the realization of the secondary function of the smart substation has undergone major changes. The functions realized by the original single device are decomposed into multiple devices, and the coupling of the function realization is greatly increased. Therefore, the performance index of the secondary function and the whole system All aspects are closely related. Due to the increase of secondary ...
