These<br \/>\n          models possess the distinctive characteristics of Japanese power systems and they have been developed with the<br \/>\n          objective of providing common system models for engineers and researchers in power system engineering.<\/p>\n<h3 class=\"p-heading-lv2 u-text-accent\">Bulk Power System Models<\/h3>\n<p>The bulk power system models are used for load flow and stability studies. The Japanese power systems<br \/>\n          comprise both 50 Hz and 60 Hz systems; from the view point of system configuration, the 50 Hz systems comprise<br \/>\n          the Tokyo area loop systems and the 60 Hz systems are characterized by a longitudinal system from the west to<br \/>\n          the east. Because the characteristics of the systems are different, each bulk power system model was developed<br \/>\n          separately. As for the scale of the systems, two middle-scale 10-machine systems and two large-scale<br \/>\n          30-machine systems were developed for the 50 Hz and the 60 Hz systems, respectively. There are in total four<br \/>\n          kinds of bulk power system models. In addition, two types of power flow conditions, daytime power flow and<br \/>\n          nighttime power flow conditions have been considered for each system model.<\/p>\n<p class=\"u-mt-line\">To successfully develop the bulk power system models, a questionnaire was conducted to<br \/>\n          reflect users\u2019 wishes; whilst, the apparatus models and the parameters are based on CRIPI\u2019s power system<br \/>\n          dynamics analysis program (CRIEPI Highly Aggregated Master-Tool of Power-System Stability \u201cCHAMPS\u201d), the<br \/>\n          Y-method which is widely used in Japan.<\/p>\n<ul class=\"u-mt-line\">\n<li><a class=\"p-link\" href=\"http:\/\/denki.iee.jp\/pes\/?page_id=496\">IEEJ EAST 10-machine system model<\/a>\n          <\/li>\n<li><a class=\"p-link\" href=\"http:\/\/denki.iee.jp\/pes\/?page_id=500\">IEEJ WEST 10-machine system model<\/a>\n          <\/li>\n<li><a class=\"p-link\" href=\"http:\/\/denki.iee.jp\/pes\/?page_id=504\">IEEJ EAST 30-machine system model<\/a>\n          <\/li>\n<li><a class=\"p-link\" href=\"http:\/\/denki.iee.jp\/pes\/?page_id=507\">IEEJ WEST 30-machine system model<\/a>\n          <\/li>\n<\/ul>\n<p class=\"u-mt-paragraph\"><a class=\"p-link\" href=\"http:\/\/denki.iee.jp\/pes\/?page_id=175\">Sub-transmission<br \/>\n            Network Models<\/a><\/p>\n<p class=\"u-mt-line\">The sub-transmission network models were developed mainly for the verification of fault<br \/>\n          restoration and reliability assessment algorithms.
