摘要
Abstract
Large-scale new energy is mainly based on offshore wind farms in the southeast coast,wind farms in the northwest and photovoltaic power plants,and the access of new energy in these areas to the large power grid system directly leads to a variety of transient overvoltages.In order to solve this kind of overvoltage problem,this paper,from the perspective of DC and AC access of large-scale new energy on land and soft and direct access of offshore wind power,aims to access a variety of transient overvoltages caused by grid faults or switching operations in large power grid systems,reviews the mechanism re-search,suppression methods and overvoltage assessment methods,etc.It is pointed out that the reactive power imbalance of the access system is the main cause of transient overvoltage in the transient process,and the suppression measures mainly include the configuration of reactive power compensation devices such as adjusting cameras and the optimization of the control strategy of the access system.However,the research on the transient overvoltage mechanism of complex fault types and the overvoltage suppression scheme coordinated by the source network still need to be further studied.Finally,the evaluation meth-ods of transient overvoltage of access system are summarized,and the evaluation requirements of multi-constraint and multi-decision variable combination are proposed.关键词
