解列和减载技术在印尼INDORAMA工程的应用

Application of grid islanding and load shedding schedule in INDORAMA Project of Indonesia

针对印尼INDORAMA电厂、IRS化工厂和印尼国家电网(PLN)构成的局部电力网络采用的解列和减载技术方案的特点、逻辑功能和应用情况进行了介绍。在该方案的制订和实施过程中,不仅考虑了国内电力系统规程(规范)的要求,而且也理解、吸收和融合了国外电力系统专家的经验,以保证企业自备电站在电网波动及电网发生事故时,能坚持孤岛运行为目标的逻辑理念且中西兼顾,是对企业自备电站(小电源并网系统)解列和减载方案设计和逻辑功能的总结,希望能对从事电厂建设的工程技术人员有所帮助。

The characteristic, logical function and application of grid islanding and load shedding schedule were introduced, which was applied in the partial power net composed by the INDORAMA Captive Power Plant, INDORAMA SYNTHETICS TBK and Indonesia National Power Grid （ PLN ）. In the process of formulation and implementation of the technical schedule, not only the demands of electrical system standards of China were considered, but also the experiences of abroad electric system experts were absorbed and syncretized. When the voltage of National Power Grid is failure, the schedule can ensure the Captive Power Plant can operate at islanding mode, and can shed load automatically according to the plant capacity and practical load. The schedule is summary of Capital Power Plant （ small power synchronized system} splitting and load sheding design and logical function, and it is expected that the schedule is helpful for the engineers working at power plant construction.
