Problems solved by technology

[0004] However, the batch control functions of most centralized control systems do not take into account the safety issues of control priority and mutual exclusion in multi-party control
For example, the power grid control center is controlling the active power of the wind farm for the purpose of grid security and stability. At this time, the batch startup and shutdown operations of the centralized control center may destroy the effect of the active power control and cause safety risks.
In addition, the startup and shutdown of a large number of equipment may also cause large fluctuations in the stability of the power grid
In short, the batch control function of the current centralized control system does not consider the power flow fluctuations and security and stability risks that batch control may cause to the power grid, nor does it take into account the control priority and mutual exclusion between the centralized control center and the grid control center, so there are certain security risks

Embodiment approach 1

[0030] figure 2 It is a flow chart showing a batch control method of a new energy station according to Embodiment 1 of the present invention.

[0031] Such as figure 2 As shown, the processing flow of the batch control method firstly selects the equipment sequence to be batch-controlled in the target new energy station at step 210 . As an example, multiple wind turbines 7 in the wind farm station A may be selected as equipment sequences to be controlled in batches. Additionally, a sequence of device numbers may be utilized to represent the selected sequence of devices.

[0032] Next, in step 220, the batch control preset is realized by performing safety lockout logic check on the selected equipment sequence, so as to determine the safety of the batch control operation.

[0033] In step 230, it is determined whether the preset of the batch control is successful or not according to the result of the safety lock logic check. Specifically, if the result of the safety lock lo...

Embodiment approach 2

[0061] In the centralized control system, batch control can be divided into two types: conventional batch control and emergency dispatch batch control. Conventional batch control is mainly used for remote batch startup and shutdown operations during daily operation or maintenance. Emergency dispatch batch control is used by the power grid regulation department to notify the centralized control center of emergency dispatch orders in case of power grid accidents or emergencies, and the centralized control center will perform operations such as emergency stop or batch shutdown of the entire site. The main difference between the two is that in the case of emergency control, the active power change of the new energy station can exceed the maximum limit value of active power change stipulated by the power system dispatching organization, while the active power change must strictly meet the specified maximum limit value requirements under normal conditions . The batch control method...

Abstract

The invention provides an efficient batch control method, a centralized control system and a communication gateway capable of ensuring the safety of remote batch control in new energy stations. The batch control method includes: selecting the equipment sequence to be batch-controlled in the target new energy station; realizing the preset of batch control by performing a safety lock logic check on the selected equipment sequence to determine the safety of the batch control operation; And when the preset of the batch control is successful, execute the batch control of the selected equipment sequence.

Description

technical field [0001] The present invention relates to a new energy station control method, in particular to a new energy station batch control method, centralized control system and communication gateway. Background technique [0002] With the construction and promotion of centralized monitoring centers (hereinafter referred to as centralized control centers) of new energy stations (including wind farms, photovoltaic power stations, etc.) System) Remotely perform early warning, monitoring, control and analysis of wind turbines, photovoltaic inverters and other equipment in new energy stations. In terms of control business, the control operations often performed by operators include equipment startup, shutdown, and reset. Due to the large number of devices in new energy stations, operators often need to perform the same type of operation on multiple devices at the same time during daily operation and maintenance. For this reason, most centralized control systems provide ba...
