摘要： PROBLEM TO BE SOLVED: To provide a rotating type total heat exchanger with a high heat recovery efficiency, which eliminates the risk of intrusion of return air. SOLUTION: The rotating type total enthalpy heat exchanger includes: a rotor which houses a heat exchange element carrying out total heat exchange of two different types of air currents of supply air and exhaust air; a supply duct and an exhaust duct for the air currents formed on both sides of the rotor; and an air supply fan and an air exhaust fan causing an air current in each of the supply duct and the exhaust duct. The air supply fan is arranged so as to push the air current into the heat exchanger, the air exhaust fan is arranged so as to draw out the air current from the heat exchanger, a rotational frequency of the air supply fan is controlled such that an exhaust duct internal pressure Pe is constantly lower than a supply duct internal pressure Ps fan like screen plates are provided in a supply side and an exhaust side of the rotor housing the heat exchange element group, and intrusion of air on an exhaust duct side into an exhaust duct side is prevented during rotation of the rotor.

摘要： PROBLEM TO BE SOLVED: To provide a power-feeding controller which keeps supplying power to an emergency power bus line load without bringing the in-station power generator to a stop even when a breaker in a substation on the transmission system side is opened and a power interruption is caused due to an interruption of incoming power during parallel operation of the transmission system from the substation and an in-station power generator. SOLUTION: The power-feeding controller includes: a power interruption detecting means which is configured to supply power to the emergency power bus line load and to a regular power bus line load other than the emergency power bus line load and detects the occurrence of power interruption on the transmission system during parallel operation; and a load cut-off means which, based on a detection signal from the power interruption detecting means, cuts off the regular power bus line load from a power generator. The power interruption detecting means commits no malfunction in detecting power interruption and detects a power interruption at high speed, so that the occurrence of power interruption is recognized when a purchase power drops below a minimum purchase power. The load cut-off means is configured to ensure high-speed cut-off, so that a load to be cut off is selectively forecasted to allow the power generator to operate continuously without excessive fluctuation of a load to the power generator during a synchronous operation.

摘要翻译：要解决的问题：提供一种供电控制器，其即使在变速器系统侧的变电站中的断路器是（或）变压器的情况下，也不会使站内发电机停止而对应急电力总线负载供电，并且由于在变电站和站内发电机的并联运行期间中断输入功率而引起电源中断。供电控制器包括：电源中断检测装置，其被配置为向紧急电力总线负载供电，并且向紧急电源总线负载以外的常规电力总线负载供电，并检测发生并联运行时传输系统电源中断; 以及负载截止装置，其基于来自电力中断检测装置的检测信号，切断来自发电机的常规电力总线负载。电力中断检测装置在检测电力中断时不会发生故障，并且在高速度下检测电力中断，从而当购买电力低于最低购买电力时识别电力中断的发生。负载截止装置被配置为确保高速切断，从而选择性地预测要切断的负载，以允许发电机在同步操作期间连续工作而不会对发电机的负载过度波动。版权所有（C）2009，JPO＆INPIT
