Technical renovation and overhaul is the essential link of the development of power system, the main problem is to solve the technical problems and operational risks, optimize the application of grid technology, and strengthen the reliability of power grid operation. Technological overhaul project is a system engineering, project from the project application, capital investment to the implementation of the project, schedule management and project evaluation and acceptance, every link need careful planning, to the successful completion of the work, the management of each link must be effectively put in place and play the greatest role in technological overhaul project, effectively avoid the potential risk of power grid operation, safeguard the stability of power grid operation.
1 management analysis of technical renovation project
At present, the management level of the electric power grid system in China is uneven, and many projects have problems in the management process, which directly affects the safe operation of the power network. Combined with the practical application of the technical renovation project in electric power industry, the main problems existing in the project management are analyzed.
1.1 cost control problem
Electric power enterprises in carrying out technological overhaul project fails to fully evaluate assets within the enterprise, cannot provide a stable cost for the overhaul of the technological transformation, and thus lead to less than the cost or control problem, lead to technological overhaul process waste a large amount of capital cost [1]. Technological overhaul project management in and need to cost inputs in the aspects of the implementation of the basic control and planning, establishment and optimization of technological overhaul project, to prevent the emergence of technological overhaul project cost overruns.
1.2 technological transformation design is unreasonable
Electric power overhaul project, the need to design the project to take a detailed management, is committed to the specific situation of the power equipment through detailed research, in order to propose a reasonable technical renovation project plan. In the management of practical technical renovation project, some enterprises have ignored the importance of engineering design because of the excessive pursuit of economic benefits, which has reduced the technical level of technological innovation, and did not meet the management requirements of the technical renovation project.
1.3 technical renovation project practice is low
Electric power enterprise technological overhaul process, due to the low level of management is prone to practical implementation is not in place, causing lots of unexpected situations, become a technological overhaul project beyond the control of the influencing factors, so such emergencies increased difficulty of management, reducing the technical modification of overhaul project practice, lead to technological overhaul is difficult to achieve the original target and, which is technological overhaul project management in the most intuitive.
2 strengthening measures for technical renovation project management
In view of the defects of the cost control, technological innovation design, practice and so on, the corresponding solutions are put forward to strengthen the management of technical renovation project.
2.1 strengthen cost control
Strengthening cost control in the management of electric power enterprise technological renovation project management. The first electric power enterprises in the implementation of technological overhaul, should clear assets within the enterprise, fixed assets, detailed records of various categories such as transmission, substation and other parts, the cost of providing reference for the technological overhaul; management and technological overhaul project cost standard, make the cost of technological overhaul project, to control the within the scope of management standards, reduce the project cost to the greatest extent, but also reduces the risk of cost overruns; finally in the technological overhaul project cost management and control, introducing costing, provide relevant model for technological overhaul project management cost control, strict control of project cost.
2.2 improve the technical renovation project design
Electric power enterprises in the technological transformation and overhaul projects, must have a sound technical renovation project design [2]. mainly from the following several aspects:
(1) to evaluate the operating status of the power grid system and the key points of the technical renovation and technical renovation, and to define the project contents of the technical renovation in accordance with the requirements of the power system.
(2) in the management of technological innovation, especially in the design of the project, we must take the power enterprise management as the main power, so as to improve the management benefit of the technical renovation.
(3) select a professional enterprise to assist in the design of technical renovation project and the implementation of scientific management, to prevent the project design quality problems.
2.3 implementation of technological transformation projects
Power grid renovation projects should improve the ability of management practice, and actively implement the practice of management, management and control of the technical reform of the sudden factors, to rule out the interference of emergency overhaul project. Technological overhaul management should be based on the actual project and promote the project and management of the coordinated development, to avoid the contradiction between or deviation, which can play project management in technological overhaul reliability. The electric power enterprise can according to the content of technological overhaul project, the planning of a possible emergency situations, advance the development of contingency plans and management measures, reduce the burstiness of the technological overhaul project in destruction.
3 methods to improve the project management of technical renovation
Weak point in the first in-depth study of various power equipment performance and safety conditions, find out the equipment and the performed tests of, according to the contents of the inspection report, arrange overhaul renovation project and to develop a management plan, master grid technological overhaul project conditions and content, in order to take scientific and reasonable management methods, so as not to affect the management effectiveness.
Second the contents of the overhaul project of technical renovation project are studied, and the problems of the research are put forward to solve the problems in management. The management of technical renovation projects must meet the standards of policy or system, and the management standard of the technical renovation of power network is needed, and the contents of the system need to be approved by the national power grid.
Third because of the wide range of power grid renovation projects, and the project implementation staff skills level is not unified, so it is necessary to take the necessary safety supervision mode, to identify the hidden dangers in the management, and put forward preventive measures to avoid the risk of management. Safety supervision is an effective method to improve the management level of technological innovation and management. It can improve the management of project design, and improve the management level of the project.
4 concluding remarks
Technological overhaul project is an important part of the power in the process of enterprise development, improve the management level of the technological overhaul, conducive to the implementation of the practice and application of advanced technology in power system, through the project management for technological overhaul provides the most direct way to control, eliminate projects, potential risks and hazards, optimization of technological overhaul project execution and promote the positive development of network business.
