Problems solved by technology

However, no matter what measures are taken for software and hardware, when an unforeseen disaster such as fire strikes, the existing monitoring system will still fail in an instant
[0005] Although it is not difficult to think of a plan to establish a remote disaster backup system for important systems, it is obvious that the investment is large and the operation and management costs are high. As far as the current national conditions are concerned, it is not feasible

Embodiment 1

[0035] The method for establishing a power grid monitoring disaster backup system in this embodiment is as follows figure 1 As shown, the two remote computer network management systems that are connected to substations and can operate independently are the existing regional dispatch automation system (EMS system) and the newly built substation centralized control system (SCADA system). The two systems can realize data synchronization and sharing in this system through their respective network management programs (dnet), and their hardware consists of the following parts:

[0036] Front-end data acquisition unit-used to collect and receive information from each substation in real time, and transmit it to the front-end server;

[0037] Front-end server-convert the information transmitted from the front-end data acquisition unit into engineering information and then send it to the database server of this system;

[0038] Main and standby database servers (hereinafter referred to as ...

Abstract

An optical semiconductor device contains P type semiconductor substrate, P type epitaxy layer, N type cathode surface layer, optical receiving component formed of P type epitaxy layer and cathode surface layer, micro reflection mirror area formed from channel part, semiconductor laser chip fixed on bottom of channel part, and anode buried layer, so the optical receiving component having high speed action and high optical receiving sensitivity and luminous component having semiconductor laser chip can be integrated in one substrate.

Description

Technical field [0001] The invention relates to a method for establishing a power grid monitoring disaster backup system, in particular to a method for establishing a power grid monitoring remote disaster backup system realized by means of remote network interconnection, and belongs to the technical field of power grid monitoring facilities. Background technique [0002] With the improvement of power system automation, the production operation, command and dispatch of power grids increasingly rely on various computer monitoring systems. The Chinese patent application with application number 02110057.8 discloses a real-time monitoring and analysis system for a power supply network. The system is composed of a power collection terminal connected through RS-485 and a main station processing terminal. With the help of data exchange and processing between them, Automatic multi-directional detection of the user’s power consumption; while the Chinese patent application No. 03136931.6 di...
