Abstract

Provided is a constant value checking system of a power grid protecting device. The constant value checking system comprises a first database server, a second database server, a dispatch working station, a first working zone working station, a second working zone working station, an intranet exchanger A, an intranet exchanger B, a first communication server, a second communication server and an application server. The first database server and the second database server are connected with the intranet exchanger A and the intranet exchanger B respectively. The first database server and the second database server are connected with each other through a disk array. The first communication server and the second communication server are externally connected with an outer net exchanger which is externally connected with a substation through a longitudinal encryption device and a router and then via a dispatch data network. The application server is externally connected with a safety III zone through a forward partitioning device. The safety III zone comprises a WEB server, a firewall and an III zone exchanger which are connected in sequence. The III zone exchanger is connected with an OMIS server and an III zone office network user computer. Efficiency is high, data cannot be lost, a protection debug port is not occupied, constant value checking can be carried out for a transformer substation, and the constant value checking results can be looked up at an office computer.

Description

technical field [0001] The invention relates to a fixed value check system of a power grid protection device based on a credit guarantee system, in particular to a system for realizing the fixed value check of a power grid protection device based on the existing credit guarantee and OMIS systems. The invention also relates to a method for checking the fixed value of the power grid protection device using the system. Background technique [0002] Nanjing Nanrui Relay Protection Co., Ltd. "an automatic checking system for protection device setting" realizes setting value checking in the substation by using the dispatching data network to download the grid protection device setting value sheet from the provincial company WEB server, and downloading the setting value through the protection debugging port. The nuclear program realizes the fixed value check of the protection device in the station. [0003] There are following deficiencies in this scheme: [0004] 1. The provinci...
