Facing the five contradictions of power informatization

the power informatization market, which has been warmly pursued by it manufacturers, does not seem to "explode" with the promotion of power system reform. On the contrary, it seems to be more calm under the background of increasingly serious "power shortage"

power enterprises are busy coping with the "power shortage", the five power generation groups are busy formulating informatization plans, while power generation enterprises have suspended many informatization projects due to the change of "owners", and only the informatization of power marketing is advancing steadily. Where is the "Crux" of the stagnant power information market? How long will the impact of power system reform on power informatization last

on the basis of in-depth investigation, this paper summarizes five pairs of "contradictions" in the power information market: advanced automatic control system and lagging management system, complex system and blank standard, market fire and disorder of competition, heavy tasks and weak organization, lack of planning and system division. Therefore, it is believed that these five pairs of "contradictions" affect and restrict each other, Together, there are many problems in the power information market

China's power generation production automation monitoring system and power dispatching automation system have long been at the international leading level, but due to the long-term monopoly of the power industry and the continuous adjustment of the management system, its management information system lags behind a lot

advanced automatic control system and lagging management system

power informatization includes power production, dispatching automation and management informatization. Power plant automation has always been the focus of power informatization. Most hydropower plants, thermal power plants and substations are equipped with computer monitoring systems; A considerable number of hydropower plants have also realized unattended and few people on duty after the transformation. The wide application of automatic monitoring system in power generation greatly improves the automation level of production process. The automation level of power dispatching is even more advanced in the world. At present, various systems of power dispatching automation, such as SCADA, AGC and EMS, have been built. All provincial power dispatching agencies have established SCADA systems, and 100% of the three-level power dispatching has been automated. Guoziming, director of the Automation Department of North China Power Dispatching Bureau, said that as early as the 1970s, North China Power Dispatching bureau used transistor computers to dispatch power, from domestic 121 machines to 176 machines, and then to 176 double machines. North China Power Dispatching bureau used all of them, and by 1978, it had basically realized power dispatching automation. Now the North China Power Dispatching Bureau has real-time monitoring of the network ǚ 5. Continue the process of cleaning the machine, and then remove it slowly

in contrast, the construction of power industry management information system lags far behind. Even in units such as State Grid Corporation and Huaneng Corporation, the construction of management information system (MIS) is still in its infancy, mainly realizing the basic functions of OA, financial management, human resource management and so on. In the implementation of ERP, only Zhejiang electric power is still adhering to the ERP project implemented by IBM, and the power companies in Shandong, Liaoning, Hubei and other places have suspended the relevant informatization plans

an unnamed power informatization expert believes that the root cause of this phenomenon lies in the continuous adjustment of the management system of the power industry. After decades of development, power production has formed a rigorous process. For example, the equipment should be overhauled every 10 days, and the unit should be overhauled every 3 months. No matter how the management system is adjusted, it should be dispatched and managed according to a unified process, otherwise there will be potential safety hazards. The construction of management information system is directly affected by the reform of management system. From the Ministry of water and electricity to the Ministry of electric power, then to the Ministry of energy, the state power company, and the state power company, power plants belong to the local government today and to the central government tomorrow. The constantly adjusted management system not only makes power enterprises lack relatively stable management ideas, management models, and organizational structures, but also makes enterprise managers pay insufficient attention to management information systems

the head of the information center of Shunyi District Power Supply Bureau in Beijing complained that the MIS management system had just been built. After a short time, an order came down, the ownership changed, the enterprise leaders changed, and the system had to be changed again. The enterprise couldn't stand this kind of toss

another important reason for the lagging management information system is the long-term monopoly of the power industry. The driving force of informatization comes from the pressure of market competition, and power enterprises not only monopolize sales, but also supply exceeds demand. As long as the generator set is running, the "money printer" will not stop, and the direct impact of management information system is small. This "natural shortage" of source power has seriously affected the attention of power enterprises to management informatization. A marketing director of an IT enterprise said that in recent years, although some power enterprises have also embarked on some informatization projects, the thunder and rain are often small. Because there is no pressure from the market and cost, the proposed demands are virtual and cannot be operated at all, and even informatization can only be regarded as a political performance project

however, with the deepening of the reform of the power system, the demand of power enterprises for management information system is becoming stronger and stronger, which is mainly reflected in the need for power generation groups to strengthen the management of subordinate power generation enterprises, and the need for provincial and county power supply companies to improve enterprise efficiency. Wu Xingping, general manager of China Power Purdue, gave an example. At present, the power generation group urgently needs to know the operation of its subordinate enterprises that day, but it can't monitor the operation of each unit. It is often unreliable to rely on human reported data, such as whether the shutdown is planned or unplanned, which will force the power generation group to speed up the construction of management information system

power generation enterprises not only need to strengthen the construction of management information system, but also need to integrate management information system and automatic control system to make the oil flow back to the oil tank from the main oil cylinder of the oil pump through the oil return valve. But how to realize the integration is still controversial: one view is that the MIS of power plant can directly extract data from the automatic control system; Another view is that CIS system should also be established between MIS system and automatic control system, and materials from the same material group should be adopted. CIS system first extracts data from various scattered automatic control systems, then collates the data, and then extracts part of the data into MIS system

at present, various application systems of China's power system have developed many coding systems according to their own needs, but they can't be popularized across the country. Many units are developing standards, but no one counts. The root cause lies in the insufficient demand of users

The large and small gear samples are installed in the experimental gearbox of the gear machine. The complex system and the blank Standard

the blank of the power informatization standard is also an important reason for the lag of the management information system. Just like a building, if the decoration styles of each house are different and the line settings are not connected, even if the decoration of each house is perfect, the management of the whole building is still in chaos. The same is true of information construction. Without a unified industry standard, information sharing between different units cannot be achieved, and first-class software companies cannot be cultivated. Conversely, if there is no first-class software company, the level of information construction in the whole industry will not be significantly improved

in 1984, China and France cooperated in the construction of Daya Bay nuclear power plant. The first expert sent by France was not a nuclear power expert or a construction expert, but a document expert, who was responsible for preparing document codes. At that time, many people did not understand why they sent a document expert and threatened to return the document expert, but the French side insisted that the standard must be first. Now, both Daya Bay nuclear power station and Ling'ao Nuclear Power Station adopt the document standard prepared by the French expert to solve this problem. However, power enterprises such as Daya Bay nuclear power plant are a minority after all

Wuxingping, general manager of China Power Purdue, said that at present, a unified informatization standard system has not been formulated for the informatization of the power industry, and the information coding, technical standards and specifications of the internal information system of power enterprises are not unified; For the same part, the purchase department has a code, the inventory Department has a code, the production department has a code, and even the name is different. It is reported that at present, various application systems have developed many coding systems according to their own needs, some of which are used in the province, and some are used in Prefecture and municipal power enterprises, but they can not be popularized throughout the country
