The Schedule Management Optimization Of Quwo220kV Substation Installation Project

Substation construction project has a complex organizational structure, high skill level requirement, many influencing factors and so on. Identified an item of this type in production organization mode, duration, cost balancing, complex processes and technologies are constantly faced with new problems and challenges, project management at all stages of the management and control requirements getting higher and higher. Shanxi power network is located in the West-East power transmission and ultra-high voltage long-distance transmission of key parts of their power grid construction in recent years of rapid development. New substation project more and more engineering technical requirements getting higher and higher, have emerged a large number of the installed substation construction project management needs to address problems. Quwo220kV substation in Shanxi power network of key nodes, high level of comprehensive automation technology, extensive use of new technologies. Phases in project preparation, implementation and application of the substation are difficult, process of construction progress management difficulties and other issues. Many project management issues are currently in trial and error research. Specific projects to the substation construction project management provides a good combination of theory and practice opportunities.To Shanxi Quwo220kV substation installed engineering of construction management situation for cases description substation installed engineering project progress management has technology content high, and cross job more, and construction quality requires high, and has must risk, and progress target can points sexual big, progress management of levels more, features, needs height attention security high, and time sexual strong, and statistics effects surface wide, and social value highlight, special requires, turn pointed out that project progress management in substation installed engineering construction management in the of important role.Application of network planning technique in Shanxi quwo for perfect installation of220kV substation bar plans are installed Quwo220kV substation engineering network plan map. Network analysis projects at all stages of the time parameters, calculate the project critical path and duration. By comparison of actual construction and engineering progress found progress in the management of engineering construction project extensions, compress the duration (rush) did not take into account the operation fee rate, work process issues such as arrangements are not reasonable, and pointed out that he Project installation of220kV substation to the effective and efficient compression process execution time, and could lead to problems with minimum cost and duration to complete requirements are met.Based on the above description, how reasonable and effective compression of various processes of project execution time becomes a core of Quwo220kV substation installation problems. According to CPM networks mobile long study put forward the characteristics of direct compression method. Model to identify the root causes causes of maximum effective compression and free nature of the time difference, find the critical path network. One of the critical path critical path difference is needed to achieve maximum effective compression. Maximum effective compression calculated on the basis of, identify key network theory, and critical theory of networks and compressed Key.
