Electric energy quality data integration method, device and system

The invention discloses an electric energy quality data integration method. The method comprises the following steps: an electric energy monitoring point collects electric energy quality data, and sends the electric energy quality data to a kafka server in real time according to a subscription instruction; the Kafka server receives a data consuming request of a data WEB client; the kafka server searches the offset corresponding to the data consuming request of the WEB client according to the data consuming record of the WEB client, and acquires the electric energy quality data corresponding tothe offset from the kafka server, and sends the electric energy quality data to the WEB client. The data relay is performed through the kafka server, the electric energy quality data of different systems can be effectively integrated, the method can be response to the offset through the kafka server, thereby responding the electric energy quality data request of the WEB client more real time. 种电能质量数据的融合方法包括：电能质量监测点采集电能质量
