The invention discloses an online monitoring method, device and system for local market power of an electric power spot market, and belongs to the field of electric power market monitoring. For each partition, a structure index of the partition is calculated according to the relative concentration ratio and the supply and demand index of the partition, and it is judged whether the partition is abnormal or not according to the structure index; and if yes, whether the key power generation main body exists in the abnormal partition or not is judged according to the effective output electricity price and the predicted output, and if yes, whether the key power generation main body abuses the market power or not is further judged according to the reference quotation of the key power generation main body and the price threshold value of the abnormal partition. According to the scheme, firstly, whether the partition is abnormal is judged through the structure index, and if yes, whether the abnormal partition has a ke
