5. Development stage of electric power informatization

The application of information technology in my country's power industry began in the 1960s. In the initial period of electric power informatization construction, mainly in the aspects of digital calculation of electric power experiment, engineering design technology calculation, automatic monitoring of power plant, automatic monitoring of substation, etc., the goal is to improve the automation degree of power plant and substation production process, improve power production and Improve the monitoring level of power transmission and transformation, improve the calculation speed of engineering design, shorten the cycle of power engineering design, etc.

The second stage of electric power informatization development refers to the 1980s and 1990s. This period is the stage of special business application. Computer systems have been applied in business fields, and computer systems are widely used in the power industry, such as power grid dispatching automation, power plant production automation control systems, power load control forecasting, computer-aided design, computer power simulation systems, etc. At the same time, enterprises began to pay attention to the development and construction of a single system of management information for the management of various business departments.

The third stage of electric power informatization development refers to the period from the early 1990s to the early 21st century, which is a period of accelerated development of electric power system information construction. With the rapid development of information technology and network technology, especially the emergence and development of the Internet, the informatization of the power industry has been promoted to achieve leapfrog development. The application depth and breadth of information technology have reached an unprecedented level in the electric power industry. Develop and construct enterprise management information system MIS in a planned way. The application of information technology extends from the operation layer to the management layer, from a single machine and a single project to a networked, holistic and comprehensive application. The construction of network infrastructure is rapid. Enterprise-level information integration applications are in full swing, and information security construction has been carried out.

Since the 21st century. Electric power informatization has reached the fourth stage. The goal of informatization construction is mainly in the aspect of management informatization, enterprise resource planning, asset and equipment life cycle management, safety production management, supply chain management, group control, intensification of personnel, property, and comprehensive budget management. Focusing on management innovation, reorganize, change and reorganize enterprise business processes, organize flat and lean management, continuously reduce costs, improve efficiency, and support enterprise management through information technology. Continuously improve the value of the enterprise, and finally establish an information enterprise.

6. Obstacles to the development of electric power informatization

The achievements of electric power informatization cannot be denied. However, the development of electric power informatization does have unbalanced development. The level of informatization among enterprises is uneven. Some business leaders do not fully understand the importance of informatization. They lack strategic planning and scientific organization. The informatization level of some enterprises is not high, the information resources are scattered, the system lacks integration, and the practical level is low. Phenomena such as low-level redundant construction exist. The integration of information technology and business is not deep, and a unified information platform that is conducive to the implementation of group operation, intensive development, and refined management has not yet been formed, which restricts the modernization process of resource integration and enterprise management of electric power enterprises (groups).

The problems in the development of electric power informatization can be summarized into five aspects.

6.1 The lack of information planning leads to the lack of systematization in information construction, more and more application systems are built, repeated construction is serious, software development investment is large, and maintenance costs remain high. The lack of project acceptance standards makes project acceptance a formality and software application a decoration.

6.2 Lack of unified information coding, technical standards and norms; scattered data and application architecture, complex structure; lack of enterprise-level integrated system construction, information islands and chimneys, horizontal data exchange is difficult, data sharing is poor, high redundancy, The data source is not unique, and the statistical data is not accurate.

6.3 Pay attention to safe production and production automation, and despise enterprise operation management. The operation and management efficiency is low, the supply chain management system has not been established, the management is extensive, and the cost control, budget management, and asset and equipment management are weak.

6.4 Management and control are separated, the production system and management information system have not been integrated, and the integration is poor.

6.5 There is a lack of systematic training on advanced management concepts at the top and management levels of the enterprise, the management concepts are relatively backward, there is a negative attitude towards management changes, and there is a lack of innovation capabilities around organizational changes, process changes, and management models. The information system and management tools have changed, but the business process remains the same or has been changed without changing the medicine. The business departments are independent, and the coordination between departments is poor. The traditional management model of "waiting for the boss to make a decision (coordinating or balancing interests)" is difficult to change. The traditional management system makes the power enterprise management informatization demand not strong.
