| Abstract | The growing sensibility to environment issues contributed in recent years to the erection of barriers in the construction of new overhead transmission lines. One of the solutions to overcome these problems is the use of cable lines for high (HV) and extra-high (EHV) voltage. However, the coexistence of overhead and cable lines in transmission systems, in the so called “mixed” lines, raises a number of issues regarding the behaviour of such systems both in transient and steady state. In particular, the definition of angle or transient stability of a system plays a strategic role and provides the actions of design and planning of the system. The purpose of this study is to investigate the angle stability of a system containing a mixed line: a control strategy of shunt reactors, located to compensate reactive power request of cable line, will be proposed as countermeasure to severe disturbance and then as improvement of power system stability. The analysis, based on detailed time simulations, will show that the timing of control actions of shunt reactors is critical for the success of emergency control: in particular, the size and the timing of reactive power involved in switching operation determine whether these control actions play positively or not in avoiding angular separation and system instability. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
