Abstract: 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.

Key words: Indonesia INDORAMA Captive Power Plant (CPP), grid islanding and load shedding technique, logical function, application feature
