Power GUI Block: The Powergui block allows you to choose one of the following methods to solve your circuit: To deploy models to other simulation environments, including hardware-in-the-loop (HIL) systems, SimPower Systems supports Ccode generation. You can add mechanical, hydraulic, pneumatic, and other components to the model using Simscape™ and test them together in a single simulation environment. You can parameterize your models using MATLAB® variables and expressions, and design control systems for your electrical power system in Simulink®. SimPower Systems models can be used to develop control systems and test system-level performance. Harmonic analysis, calculation of total harmonic distortion (THD), load flow, and other key electrical power system analyses are automated. The libraries offer models of electrical power components, including three-phase machines, electric drives, and components for applications such as flexible AC transmission systems (FACTS) and renewable energy systems. INTRODUCTION:SimPower Systems™ provides component libraries and analysis tools for modeling and simulating electrical power systems. To understand the behavior and characteristics of SIMPOWER SYSTEM.If you want to view the nonstructural parameter differences between a reference block and its corresponding library block, choose View changes from the Link options menu.LAB EAXPERIMENT NO: 2 INTRODUCTION TO SIMPOWER SYSTEM (PLO: 5 (Modern Tool Usage)) If you want to propagate or discard the changes at a later time, select the reference block, choose Link options from the model window's Edit or context menu, then choose Propagate/Discard changes. If you restore a link with nonstructural changes, Simulink enables the link without prompting you to propagate or discard the changes. In either case, the end result is that the reference block is an exact copy of the library block. If you choose to discard the changes, Simulink replaces the modified reference block with the original library block. If you choose to propagate the changes, Simulink updates the library block with the changes made in the reference block. If you restore a link that has structural changes, Simulink prompts you to either propagate or discard the changes. Simulink allows a model to have active links with nonstructural but not structural changes. Examples of nonstructural changes include changes to parameter values that do not affect the structure of the subsystem. Examples of structural modifications include adding or deleting a block or line or changing the number of ports on a block. If you attempt to modify the structure of a subsystem link, Simulink prompts you to disable the link. If your modifications alter the structure of the subsystem, you must disable the link from the reference block to the library block. Simulink allows you to modify subsystems that are library links. To restore a disabled link, choose Restore link from the Link Options menu.
To disable a link, select the link, choose Link options from the model window's Edit or context menu, then choose Disable link. Simulink ignores disabled links when simulating a model. Simulink allows you to disable linked blocks in a model. On the dialog box that appears, correct the pathname and click Apply or Close.
#Powergui matlab simulink update
Add the directory that contains the required library to the MATLAB path and select Update Diagram from the Edit menu.Delete the unlinked reference block and copy the library block back into your model.To fix a bad link, you must do one of the following: The unresolved reference block is displayed like this (colored red).
Failed to find block " source-block-name".Simulink issues an error message and displays these blocks using red dashed lines. If Simulink is unable to find either the library block or the source library on your MATLAB path when it attempts to update the reference block, the link becomes unresolved. The library and reference blocks are linked by name that is, the reference block is linked to the specific block and library whose names are in effect at the time the copy is made. If the link is to a subsystem, you can modify the contents of the reference subsystem (see Modifying a Linked Subsystem). Also, you cannot set callback parameters for a reference block. You can change the values of the reference block's parameters but you cannot mask the block or, if it is masked, edit the mask. The reference block is a copy of the library block. When you copy a library block into a model or another library, Simulink creates a link to the library block. To create a link to a library block in a model, copy the block's icon from the library to the model (see Copying and Moving Blocks from One Window to Another) or by dragging the block from the Library Browser (see Browsing Block Libraries) into the model window.
