Introduction

Actively responding to the new security and stability challenges faced by large-scale new energy grid-connected operations has become an unavoidable issue for the power grid and new energy industries Shared responsibilities and obligations. Since.2011, with the increase in the proportion of wind power and the feed-in of large-capacity DC transmission, large-scale wind power grid integration still exists, including More safe operation risks such as frequency, fault ride-through, etc., need to start from the actual problems caused by large-scale wind farms connected to the grid, combined with China The actual situation of the power grid, considering the technical level and development trend of onshore wind farms to connect to the power grid, carry out the revision of the standards. At the same time in the country At the industry level, there is no relevant standard specifically for the technical requirements of offshore wind power access to the power system. The existing wind power grid-connected standards mainly focus on For onshore wind power, the characteristics and inherent characteristics of offshore wind power have not been fully considered, and it is also necessary to consider the technical level of offshore wind farms to connect to the grid. Carry out standard revision work in line with technological development trends. GB/T 19963 specifies the technical requirements for connecting wind farms to the power grid. It consists of two parts. ---Part 1.Onshore wind power. The purpose is to clarify that onshore wind farms are in the planning, design, construction and operation stages, The technical conditions required by the Internet. ---Part 2.Offshore wind power. The purpose is to clarify that offshore wind farms are in the planning, design, construction and operation stages, The technical conditions required by the Internet. This document focuses on the technical requirements for onshore wind power grid connection, and clarifies the necessary requirements for grid companies and power generation companies in the operation of onshore wind power grid connection. The basic technical requirements that must be met to ensure the safe and stable operation of the power grid and onshore wind farms.
