With the rapid development of power industry in recent years, the grid information technology and intelligent building is also ongoing a fast growth which brings more pilot projects and integrated projects. Because of the growing number and types of projects, it is increasingly difficult to evaluate whether the project can meet customer needs, whether the contractor is capable to undertake the projects and whether the projects are suitable for the integration of construction. This paper analyzed on the basis of the characteristics of power grid projects, combined with the basic flow of software project test and proposes a project test quantification evaluation method of project test based on multi-computing. This method achieves the quantitative appraisal of projects, selecting the best project contractor and improving the quality of the project completion through test case scores quantification and multi-computing test scores.
