A smart grid-connected control method and device for generators

Abstract

The invention relates to an intelligent grid-connected control method and device for a generator. A PLC controller reads the working parameters of the main control system of the driller's console and the working parameters of the generator in the generator integrated controller through a field communication bus; Whether there is a fault to determine whether to switch on the standby unit and cut off the faulty unit; then judge whether the current generator can meet the current power requirements to determine whether it needs to be merged into the standby unit; finally estimate the power requirement at the next moment, and determine whether to switch on or cut off generator set. The invention can predict the power usage and automatically adjust the number of generators connected to the grid, so as to realize the intelligent management of the generators, reduce the energy consumption and the wear degree of the generators; it can also be put into standby at the first time when the working unit fails. unit and cut off the faulty unit, so as to ensure the normal operation of well drilling.

Description

technical field [0001] The invention relates to the field of intelligent control of generator sets of electronically controlled drilling rigs, in particular to an intelligent grid-connected control method and device for generators. Background technique [0002] When supplying power to the electric control drilling rig, most of the generator grid-connected control cabinets are manually controlled, so professionals must be equipped to monitor in real time in the electric control room. When the units are connected to the grid, professionals are required to manually realize the grid connection. Since the personnel in the electric control room cannot accurately judge the current required power, there is often a large margin in the input power, and many redundant units are put into power generation for a long time, resulting in This reduces the waste of energy and the wear and tear of equipment; and when a certain unit fails, the staff cannot cut into the standby unit and remove t...

[0002] When supplying power to the electric control drilling rig, most of the generator grid-connected control cabinets adopt manual control, so professionals must be equipped to monitor in real time in the electric control room

When the units are connected to the grid, professionals are required to manually realize the grid connection. Since the personnel in the electric control room cannot accurately judge the current required power, there is often a large margin in the input power, and many redundant units are put into power generation for a long time, resulting in This reduces the waste of energy and equipment wear; and when a unit fails, the staff cannot switch to the standby unit and remove the faulty unit immediately, resulting in shutdown and production, and even affects the work of the entire drilling rig
