Embodiment Construction
[0024] The present invention will be described in further detail below with reference to the accompanying drawings and examples.
[0025] Such as figure 1 As shown, the two-level centralized deployment of the power supply voltage automatic acquisition system of the present invention adopts a three-layer structure of the device layer, the access layer and the master station layer. The device layer focuses on the development of stable and reliable power supply voltage acquisition and standardized data generation technology, which is a voltage monitoring device. The access layer focuses on the development of standardized access technology for data, which is a proxy device for voltage monitoring. The main station layer focuses on the development of data application technologies such as storage, processing, display, analysis and evaluation of power supply voltage information. There are two interface levels in the above layers, namely: the first level interface I1 and the second l...

The invention discloses a two-stage centrally deployed power supply voltage automatic acquisition system and a method thereof, belonging to the technical field of electric power system automatic monitoring. The present invention adopts a three-layer system framework of device layer, access layer, and master station layer, and centrally deploys monitoring master stations at the provincial power company and headquarters to realize real-time collection and transmission of voltage data, unified storage and business application. The present invention can make full use of the existing voltage data in business information systems such as dispatching and marketing, and can adapt to the data access of heterogeneous systems while ensuring the stability of the system core, saving communication and information resources; the present invention adds It is installed with a security chip and used in conjunction with the provincial security access platform. It adopts strategies such as identity authentication, encrypted transmission, and access control to realize the safe access of voltage data to the power information intranet.
Description
technical field [0001] The invention belongs to the technical field of automatic monitoring of electric power systems, and more precisely, the invention relates to a two-stage centralized deployment power supply voltage automatic acquisition system and a method thereof. Background technique [0002] As we all know, voltage quality refers to the slowly changing voltage deviation index, which is one of the important indicators of power quality. Voltage quality can be divided into grid voltage quality and power supply voltage quality. At present, in my country's power system, the collection system is mostly established at the provincial company or city level, or the method of manual input is used to collect, transmit and calculate the voltage data, and the voltage data is connected through the firewall or isolation device. Information intranet, so as to realize the monitoring of voltage quality. [0003] However, there are still some deficiencies in the current technical solut...
