General


In China, group enterprises are developing faster and faster, and they are developing gradually towards the directions of conglomeration, diversification, and cross-region and cross-model investment operation. Groups should implement their management upgrade, break the development bottlenecks and reach a higher level relying on their management control. However, they meet a lot of problems in this process. The power generation sector is no exception. In recent years, new energy has developed very rapidly, the traditional thermal power generation has been facing environment protection pressure and the energy prices have been fluctuating greatly. All the power generation groups are strengthening their business and management control. Most of them make their management control more normative, timelier, more comprehensive and more precise by leveraging information technology.


“Management control” originates from the widespread management of group-level enterprises with many branches. It emphasizes the control over the key points in the management. Relying on a series of management control design including organizations, systems, responsibilities, rights and procedures, it ensures that the business activities of the managed enterprises such as the production, operation, investment and financing are regularly carried out under the guidance of the overall strategy of the group and are controlled to enhance the executive ability of the enterprise and reduce the corporate operation risks. The “production supervision and online operation” of the power generation enterprise, as a part of the management control system, takes the production operation (production, fuel, and environment protection) and operation management (marketing and finance) as its main business part and the key supervision points. The upper level unit can timely grasp the production status and operation risks of the company and lower level units by establishing organizations, responsibilities, rights, procedures and platforms, and then the upper level unit can provide auxiliary analyses and strategic guides for the lower level units. The production supervision and online operation system is built on the basis of the fusion of all the business information (on the basis of the data center). Taking information technology as the carrier, it makes the management control of the production operation more efficient, timelier and more normative. It timely reflects the completion progress and quality of the key performance indicators (KPI) by means of information technology in the production operation process of the enterprise, timely finds the production operation risks, gives early warnings, changes the post-event management to the management of events under progress, and replaces the result analysis with the process control.


Solution


The solution is used by the management, decision-making and supervision level of the large power generation enterprise. It provides professional management control, auxiliary decision making analyses and some other application functions.


The formation of the solution is due to the following two driving forces: 1. the strategic management control of the group units — strengthening the “two promotions” and better supporting the 3-level management control strategy of China Guodian Corporation; 2. the group strategy of informationalization — implementing the 2016-2020 Planning for further Information Technology Application of the group and supporting the overall management control requirements (supporting the visible operation performance, well-controlled strategic resources, full coverage of the grass-roots unit operation and the duplicable business of the same kind).


The design thinking originates from the IT management control system customized to adapt to the enterprise development strategy by China Guodian Corporation (a group enterprise with subordinate units such as the thermal power generation plants, wind power generation plants, hydroelectric power plants and photovoltaic power plants), i.e. a five-in-one information technology application management system including production management control, operation management control, environment protection management control, development management control and risk management control;
