| 2010 is the end of the 11th Five-Year grid construction Plans and the beginning of the 12th Five-Year Plan. There will be a huge development in the next three to five years in some cities. The paper tries to find the results why there has the gap between the grid planning and the actual implements by analyzing the gap of the 11th Five-Year gird construction. The paper also tries to improve the gird planning and raise the new ideas to make the 12th Five-Year plan better.The paper is divided into seven parts.Chapterâ… is the foreword. This chapter introduces the background and the reason why the author choose this topic and how to write it. It also shows the importance of optimizing the existing planning by combining the background article and analyzing the planning gap.Chapterâ…¡, as the background knowledge, analyzes the characteristics of the planning work. The paper clearly points out that the main data in grid planning are electricity sales and the project completion rate. As the state-owned company, the paper shows that why we focus on these two data of the analysis, not general financial data, because of the state-owned company and the social responsibility.Chapterâ…¢analyzes the gap of electricity sales data. The author thinks that the main reasons affecting this data Are natural disasters, economic crisis and the inaccurate of load forecasting. The paper proposes that we should improve our method how to do load forecasting and reduce the external factors of influencing this data. The specific way is to combine the large customer load forecasting method and multi-load model to check each other.Chapter IV is focus on the gap of the project completion rate. The author considers that the influence reasons are construction funding, environment evaluation, land problem, etc. By analyzing these reasons, the paper proposes the suggestions.Chapter V combines the grid planning and the city construction planning in order to try hard to solve the external environment of grid planning and construction. The specific way is to find the balance point and integrate them together. The main purposes are to build the friendly network and the resource-saving society.Chapter VI raise that we should build the network evaluation system to reinforce the grid planning. The evaluation system should contain economic benefit, environmental benefit, social benefit, network technical performance and risk assessment. This integrated system can make the job comprehensive, accurate and reasonable.Chapter VII as the conclusion summaries the whole paper and suggestions of this paper can be the consultation to help the planning department.This paper tries to select a new point it not only analyzes the planning itself, but also analyzes the construction rate to find the gap. The paper also prefers the realistic and operational way to solve the problems.This paper also contains some shortages. We should find the most appropriate load forecasting model to calculate the exact city power grid. We should also consider the coefficient of the various data to make the evaluation system... |
