Abstract

The invention discloses an intelligent substation secondary equipment site-wide simulation test system. The system comprises a test work station provided with intelligent power network simulation software, an I / O interface module, a wireless control host and one or more wireless terminals. Each wireless terminal comprises a wireless terminal body and an intelligent terminal simulation device. The test work station is in two-way connection with the wireless control host in real time, and the wireless control host is in two-way connection with the wireless terminals through a wireless network. A plurality of related protection, measurement and control devices at intervals have access to the simulation test system, and the related protection, measurement and control devices and intelligent substation secondary equipment form the closed-loop simulation test system together to achieve overall test of the secondary equipment. According to the simulation test system, the wireless terminals are distributed beside on-site devices at different intervals and are connected on site, the wireless terminals are connected with the test work station in a wireless mode, debugging personnel do not need to carry optical fibers, and the system is convenient to build and high in environment adaptability.

Description

technical field [0001] The invention relates to an intelligent substation secondary equipment simulation test system, in particular to an intelligent substation secondary equipment whole station simulation test system. Background technique [0002] The basic requirements of smart substations are digitization of station-wide information, networking of communication platforms, and standardization of information sharing. Compared with conventional substations, the secondary system architecture of smart substations has undergone great changes. The first is the distributed configuration of relay protection. According to the general design requirements of the State Grid Corporation of China for intelligent stations, the protection of the interval layer of intelligent substations with a voltage level of 220kV and above is arranged in the protection room, while the process layer merging unit and intelligent terminal are arranged in the local intelligent control cabinet, and the equ...
