Abstract

Short circuit analysis of electrical power supply building # 71 BATAN has been carried out. The electric power supply system in building # 71 consists of the main electrical power supply from PLN of 2500 kVa and an emergency power supply supplied from a diesel generator that supplies office lighting and a nuclear standard laboratory of 200 kVa. The purpose of this study is to study the emergency power supply protection system components as well as the normal short circuit current, because the power supply system in nuclear power plants has a high safety margin. The load that is loaded consists of a mixture load of either 3 phases or 1 phase in the amount of 50 kVA, and the lighting load is 36 kVA. From the analysis using ETAP software which consists of short phase to ground, between phases, showing the value of short circuit current flowing in each system and component, the current of short circuit is 64.6 kA the existing CB panel bus of the system is 80 kA, it means the safety margin is still far above that installed. This value is used to evaluate the rating of low power nuclear power supply protection systems between 3 MW to 10 MW, with 200 kVA emergency power supply.Short circuit analysis of electrical power supply building # 71 BATAN has been carried out.

核电厂电气保护系统案例可靠性研究中BATAN 71号供电楼的短路分析

对巴丹71号供电楼进行了短路分析。71号楼的供电系统由PLN提供2500千伏安的主电源和柴油发电机提供的应急电源组成，柴油发电机提供办公室照明和200千伏安的核标准实验室。由于核电站供电系统具有较高的安全裕度，本研究的目的是研究应急供电保护系统的组成以及正常短路电流。所载负载由3相或1相的混载组成，量为50kva，照明负载为36kva。利用ETAP软件分析，由短相到地、相间组成，显示出各系统和各部件的短路电流值，短路电流为64.6 kA，系统现有CB板母线为80 kA，说明安全裕度仍远高于安装。该值用于评估3mw至10mw的小功率核电源保护系统的额定值，具有200kva应急电源。对巴丹71号供电楼进行了短路分析。71号楼的供电系统由PLN提供2500千伏安的主电源和柴油发电机提供的应急电源组成，柴油发电机提供办公室照明和200千伏安的核标准实验室。由于核电站供电系统具有较高的安全裕度，本研究的目的是研究应急供电保护系统的组成以及正常短路电流。所载负载由3相或1相的混载组成，量为50kva，照明负载为36kva。利用ETAP软件分析，由短相到地、相间组成，显示出各系统和各部件的短路电流值，短路电流为64.6 kA，系统现有CB板母线为80 kA，说明安全裕度仍远高于t。
