Talking about the new changes brought by the intelligent power consumption information collection system to the power marketing management. Based on the analysis and prospect of the construction and application of the power consumption information collection system, combined with the current situation of State Grid Hebei Power Supply Co., Ltd., this paper discusses the new changes brought by the construction and application of the power consumption information collection system to the power marketing management. From 2065438+2004, according to the requirements of "full coverage, full collection and full cost control", the company made every effort to promote the full coverage construction of the electricity information collection system, and gradually popularized the application of intelligent watt-hour meters. In accordance with the principle of "one piece of construction, one piece of application", the branch lines will promote the construction work in a unified way. During the construction, the company combined with the meter reading work, installed the watt-hour meter in rotation every month, and formulated a detailed construction plan for the electricity consumption information collection system. The company further strengthened management and supervision. Each power supply station set up a special person to be responsible for the collection, distribution, supervision and installation of concentrator, established an electronic ledger and the collection and reporting of the old table bottom on site, refined the plan to the day, established a daily summary, weekly notification and monthly assessment mechanism, promoted the project progress in a reasonable and orderly manner, strictly controlled the site safety management, standardized supporting service measures, and strictly controlled the project acceptance, thus effectively ensuring the project progress and quality. At the same time, the company further deepened the application of electricity consumption information collection system, carried out targeted application training, and appointed a special person to be responsible for electricity consumption information collection, mainly publicizing the necessity and practicability of the construction of electricity consumption information collection system, and training the ideas and methods of data association and common faults analysis and processing of the collection system and marketing SG 186 system. This paper focuses on the process of gradually changing the table of the station gateway and the whole debugging process in the construction of the acquisition system, so that every trainee can fully understand all aspects of the acquisition system and improve the business skills of marketers at all levels. As an important part of smart grid system construction, the power information collection system construction project continuously deepens the application of the achievements of "full coverage, full collection and full cost control" of power information system, constantly innovates the management mode of electricity fee copying and collection, implements the "centralized copying and collection" mode of power information throughout the county, realizes centralized control and processing of meter reading, accounting, charging, collection and operation, seamlessly connects with the construction of "big marketing" system, and optimizes and adjusts the organizational structure.
3 company electricity information collection system application effect
3. 1 line loss management
In the traditional mode, meter reading in some stations is not timely, and there are misreading and omission problems, so it is difficult to truly and accurately reflect the line loss. In order to improve the accuracy of metering collection and reduce the line loss rate, the company upgraded the original metering devices in batches in strict accordance with the unified deployment and requirements of the transformation of the electricity consumption information collection system of provincial and municipal companies. The application of smart meters not only effectively solves the problem of inaccurate measurement of customers' old meters, but also realizes the real-time calculation of line loss by monitoring the operation of metering devices in real time, and tracks and handles the abnormal fluctuation of line loss in time, effectively reducing the comprehensive line loss and improving power supply.
3.2 Power inspection
At present, the company uses the acquisition system to carry out real-time measurement of metering data and online monitoring of abnormal electricity data for all stations and users, which has achieved immediate results of accurate positioning, key inspection and investigation of electricity theft. The acquisition system is used to monitor customers' electricity consumption and possible meter failures, wiring errors, voltage and current anomalies, etc. , analysis and judgment in the background, according to the need for on-site processing, to avoid something to the scene, improve the standardized, refined and efficient management of electricity inspection.
3.3 Measurement management
Through the construction of electricity consumption information collection system, the company vigorously popularized intelligent electric energy meters, which effectively solved the problems existing in the use of old mechanical watches and electromechanical electric energy meters, such as difficult charging, reduced meter sensitivity, inaccurate measurement and so on, effectively promoted the intelligent development of metering devices, and improved the professional, standardized and refined management level of metering.
3.4 Reduce costs and improve efficiency
With the support of the system, remote meter reading can be realized, and the workload of fee collection can be effectively reduced by realizing local fee control or remote fee control. Realizing remote meter reading liberated the original meter reading class, and 160 meter readers were assigned to 10 power supply stations in the county, which enriched the power grid construction and fault maintenance team. The power supply station stopped using the temporary workers originally hired, which saved more than 100 people's expenses for the company and achieved the effect of reducing costs and increasing efficiency.
4 Outlook and Plan
According to the needs of the system construction of "three sets and five majors" and "big marketing", the power supply company plans to achieve the construction goal of "full coverage, full collection and full cost control" of electricity information collection for low-voltage residents, private transformer users and public transformer stations within its jurisdiction in 20 14. At the same time of system construction, the company will continuously improve the functions of the electricity information collection system, deepen the application of the system, build an intelligent electricity service platform based on the collection system and centered on the marketing information system, and integrate key technologies such as intelligent electricity management, two-way interaction of intelligent services, intelligent metering, and distributed power access at the client, so as to realize real-time interaction of energy flow, information flow and business flow between the power grid and customers. Form a new mode of power supply and consumption with extensive customer participation, rapid market response, flexible service mode, optimal resource allocation and multi-party cooperation, enhance intelligent and interactive service capabilities, and support smart grid construction and sustainable development of the company.
