The invention discloses a grid-load interaction terminal capable of removing a great user load quickly. The terminal comprises a real-time collection control electric plate and an electric quantity unvarnished transmission electric plate, wherein the real-time collection control electric plate acquires voltage and current of a service line and an outgoing line of a user and switch position signals and uploads the voltage, current and switch position signals to a master station in the area I in real time, so that real-time collection of a user line load is achieved; the electric quantity unvarnished transmission electric plate acquires user side meter data and uploads the meter data to an electricity information acquisition system in the area IV, so that electricity information of the user is acquired remotely and real-time monitoring of the user load is achieved; furthermore, when an ultra-high voltage grid fails, the real-time collection control electric plate receives a bulk quick control instruction directly given out by the master station in the area I, the control instruction is quickly converted into a breaking-closing relay signal, a corresponding minor load line on the user side is quickly removed, and quick response to severe power grid accidents by quick load removal is achieved.
Description
technical field [0001] The invention relates to a network-load interactive terminal capable of quickly removing large user loads, and belongs to the technical field of electric power system intelligent control. Background technique [0002] With the advent of the global energy Internet era, the proportion of UHV loads continues to increase, and the future power grid will face the challenge of UHV large receiving end power grids. The problem of insufficient dynamic reactive power compensation caused by large-scale UHV DC centralized feed-in is becoming more and more prominent, and there is a huge risk of voltage instability; Bipolar blockage due to blockage and other reasons will lead to a sharp drop in grid frequency. In an emergency, it is necessary to quickly remove some large user loads. The existing load control terminal mainly uses 230M wireless private network and GPRS wireless public network to communicate with the main station, and receives the command issued by the...
