| Abstract | The objective of this study is to determine the critical receiving power ratio (CRPR) of a receiving system fed only by high-voltage DC transmission lines. The approach is to check the voltage response when a severe fault occurs in a simplified asynchronously connected receiving system. The DC power limit is found by continuously increasing the DC power until the voltage cannot recover from the severe fault. The topic is expanded as follows. First, a simplified system model is established under a few reasonable assumptions. Then, the analytical voltage response expressions when a three-phase short-circuit fault occurs are developed, taking the effect of commutation failure, fast AC voltage control and load characteristics into consideration. The expressions of the DC power limits under different load characteristics are deduced from the analytical voltage response expressions. Besides, several crucial factors that limit the infeed power capacity of an asynchronously connected receiving system are discussed in this study based on the sensitivity analysis of the DC power limits. The CRPRs of a receiving system with different crucial characteristics are found through time-domain simulation with detailed models. The validity of the analytical voltage response expressions and the crucial factor analysis is well proved by the simulation results. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
