These power systems are exposed to different environmental conditions which may cause faults to occur on the system. Different types of studies are usually done on electric power systems to determine how the system behaves before, during and after a fault condition.

Optimum operation of the power system depends largely on the operator`s ability to provide reliable, stable and uninterrupted services to customers. Power system stability has been recognized as an important problem for secure operation. This paper presents a detailed analysis of the transient stability of a large HVAC power system.

The stability level of the weakest generator in the network was analysed by determining the critical fault clearing time (CFCT) fo...","internal_url":"https://www.academia.edu/27293217/Detailed_power_system_transient_stability_analysis_using_expert_system_concepts_and_stability_improvement_of_a_large_multi_machine_HVAC_network_using_HVDC_technologies","translated_internal_url":"","created_at":"2016-07-26T23:59:38.554-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":51401398,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[{"id":22794715,"work_id":27293217,"tagging_user_id":51401398,"tagged_user_id":208377097,"co_author_invite_id":5083618,"email":"i***4@gmail.com","display_order":0,"name":"Kamati Mbangula","title":"Detailed power system transient stability analysis using expert system concepts and stability improvement of a large multi-machine HVAC network using HVDC technologies"}],"downloadable_attachments":[],"slug":"Detailed_power_system_transient_stability_analysis_using_expert_system_concepts_and_stability_improvement_of_a_large_multi_machine_HVAC_network_using_HVDC_technologies","translated_slug":"","page_count":null,"language":"en","content_type":"Work","owner":{"id":51401398,"first_name":"Inno","middle_initials":null,"last_name":"Davidson","page_name":"InnoDavidson","domain_name":"wwwcput","created_at":"2016-07-26T23:58:23.312-07:00","display_name":"Inno Davidson","url":"https://wwwcput.academia.edu/InnoDavidson"},"attachments":[],"research_interests":[],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="27293206"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/27293206/Power_System_Modeling_and_Fault_Analysis_of_NamPower_s_330_kV_HVAC_Transmission_Line"><img alt="Research paper thumbnail of Power System Modeling and Fault Analysis of NamPower鈥檚 330 kV HVAC Transmission Line" class="work-thumbnail" src="https://attachments.academia-assets.com/47552146/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/27293206/Power_System_Modeling_and_Fault_Analysis_of_NamPower_s_330_kV_HVAC_Transmission_Line">Power System Modeling and Fault Analysis of NamPower鈥檚 330 kV HVAC Transmission Line</a></div><div class="wp-workCard_item wp-workCard--coauthors"><span>by </span><span><a class="" data-click-track="profile-work-strip-authors" href="https://independent.academia.edu/KamatiMbangula">Kamati Mbangula</a> and <a class="" data-click-track="profile-work-strip-authors" href="https://wwwcput.academia.edu/InnoDavidson">Inno Davidson</a></span></div><div class="wp-workCard_item"><span>Journal of Power and Energy Engineering</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Electric power systems usually cover large geographical areas and transmission facilities are con...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Electric power systems usually cover large geographical areas and transmission facilities are continuously increasing.
