Taking the main on-line monitoring system of primary equipment in substation as an example, there are: on-line monitoring of capacitance and dielectric loss of capacitive equipment; On-line monitoring of full current and resistive current of metal oxide arrester: on-line monitoring of transformer insulation oil chromatography, optical fiber temperature measurement, UHF partial discharge of body, partial discharge of bushing, dielectric loss and dynamic characteristics of on-load switch; GIS UHF partial discharge online monitoring and micro-water online monitoring; Switch mechanical characteristics monitoring, switch cabinet optical fiber temperature online monitoring, SF6 gas density online monitoring, etc.
According to the data of China Power Equipment Industry Competitiveness Analysis Report Outlook, the online monitoring product market is mainly concentrated in smart grid substations. State Grid Corporation of China also regards the construction of substation condition monitoring system as an important content of smart substation in its smart grid planning report. The intelligent substation realizes on-line monitoring of main equipment and important parameters such as transformer oil chromatography, partial discharge of combined electrical appliances and full current of lightning arrester through state monitoring unit, which provides basic data support for power grid equipment management. The expert system can analyze and process the real-time state information, make preliminary decisions, and realize the self-diagnosis function of intelligent equipment in the station.
In 20 12, State Grid Corporation put forward the concept of intelligent transmission line for the first time, which extended the on-line monitoring from substation side to line side. The main contents were monitoring the vertical radian of transmission line, preventing the invasion of pole tower, and micro-meteorology of line section. And transmit data through OPGW optical fiber network or wireless public network, analyze the transmission line status in real time at a long distance, and realize advanced applications such as dynamic capacity expansion.
function
After the system is used, the following functions are mainly realized: sales staff can log in to the company's internal server conveniently and safely to inquire about the progress of their own contracts; Can receive all kinds of notices from the company in real time; Contract management system replaces manual bookkeeping; The contract review among business, production and design can be completely completed online, improving efficiency; Electronic delivery; Automatic generation and printing of financial invoices. After the stable operation of the first phase, the software team will continue to establish the second and third phases of the project according to the needs of the marketing department, and complete the functions of salesman expenses, market analysis and investigation, market dynamic statistics, customer management, electronic orders, after-sales service and so on. To support enterprise management and decision-making!
The pre-sale stage of customers is basically not divided, and the leaders of branches, institutes and entity subsidiaries are very concerned about sales information (including accounts receivable and payment back), but these information can only be obtained from the financial department irregularly, lacking effective, real-time and comprehensive monitoring of the sales process from the business level. As a result, most sales are in a blind state, and the tracking of current sales opportunities has not formed a feasible mechanism.
