III. preliminary work requirements for 330kV and above power projects

first, strictly implement the national power plan. The state has launched the preparation of the 14th five year plan for electric power, and the company has prepared the 2019 version of the power plan to determine the power projects from 2020 to 2022. For the power projects that have been included in the company's plan but have not been included in the national plan, all units can carry out the project feasibility study and preliminary work first, and submit the approval request after being included in the national plan; For power projects not included in the company's planning, all units shall not start the feasibility study and related preliminary work

second, effectively improve the efficiency and benefits of the project. All units should give priority to the power projects to improve the UHVDC transmission capacity. For the frame optimization project of transmitting the UHVDC supporting power and improving the DC transmission capacity in operation, it is necessary to open up a green channel, compress the preliminary work processing cycle, and obtain approval as soon as possible; For its new UHV DC supporting power project compared with carbon fiber composite materials, according to the principle of synchronous planning, synchronous construction and synchronous production, the preliminary, investment and construction work plans are formulated as a whole to ensure effective connection

third, carefully prepare the spatial layout plan of power facilities. All units should comprehensively sort out the needs of power construction projects, prepare the spatial layout planning of trans provincial and trans regional transmission of 220 kV and above, and distribution power facilities of 110 kV and below, and strengthen the precise docking of power planning with national and local development planning and land and space planning according to the requirements of one port external level by level docking, and fully consider local government planning, land use, transportation, environmental protection, overburden minerals and other factors, Ensure that the projects included in the plan are timely, complete and accurately included in the land and space planning at all levels

fourth, comprehensively strengthen the integrated management of feasibility study design. At present, except for some provincial units, the company system has carried out the integrated management of feasibility study and design of power projects, and the feasibility study quality, work efficiency, professional connection and other aspects have been effectively improved. In the next step, all units should strengthen the integrated management of feasibility study and design, and clarify the division of labor and optimize the workflow in accordance with the measures for the management of feasibility study of power projects of national household appliances Co., Ltd. from a domestic perspective (Trial) (rules and regulations No.: National (development/2)), Strengthen the design, review and quality management in the feasibility study stage, ensure the consistency of the feasibility study and design technical scheme, and effectively improve the quality of the feasibility study design

fifth, give full play to the role of segment support management. As an important part of the feasibility study and preliminary work management of power projects, the division should play a practical role. It is mainly responsible for organizing and carrying out the feasibility study of cross provincial 750 and 500 kV power projects and headquarters and divisional expansion power projects in the region, participating in the feasibility study and preliminary work of UHV projects in the region, and at the same time, carrying out verification and evaluation for the planning and implementation of feasibility study approval of 330 kV and above power projects in the province, and the reasonable compliance of major technical principles, Relevant information shall be reported to the headquarters in time

all units often divide the power spectral density curve into several rectangular and triangular 00 kV and above AC and DC project preliminary work plans according to the company's power project preliminary work management measures and the above UHV and trans provincial 5, and submit official documents to the company's headquarters for filing before March 10
