The invention relates to a fin stabilizer closed hydraulic system with a flushing loop, which comprises the flushing loop, a motor (6), a fin rotating plunger pump (7), an oil supplementing pump (8), an oil supplementing overflow valve (9), a fin rotating overflow valve (10), a one-way valve I (11.1), a one-way valve II (11.2), a one-way valve III (11.3), a one-way valve IV (11.4), a fin rotating oil cylinder (12), a cooler (15) and an oil tank (16). When the oil supplementing pressure is higher than the switching pressure of the hydraulic control reversing valve (4), the hydraulic control reversing valve (4) is switched to be opened to achieve automatic flushing, and when the oil supplementing pressure is lower than the switching pressure of the hydraulic control reversing valve (4), the hydraulic control reversing valve (4) is switched to be closed, and the flushing loop is automatically closed. According to the system, by adjusting the flushing amount and opening and closing the flushing loop in real time,
