IscNetwork
This object provides the main access to an IPSA network. It is generally created as the result to a call to IscInterface().ReadFile(strName). This class provides functions to retrieve, create and delete network components, perform analysis and get network results.
Network Component Functions
Various functions are provided to allow the creation, deletion and editing of network components. The Get… functions return instances of the component objects, for example GetBusbar returns an IscBusbar instance. Once an IscBusbar instance is retrieved the busbar data can then be accessed as described in the IscBusbar section.
Component Access
The dictionary keys are the Python script names of components whilst the values are the instances of components. The Python script name can be used to access individual components.
The example code below details how it is possible to iterate through all the components of a particular type in a network:
# retrieve the busbar collection
busbars = net.GetBusbars()
# cycle each busbar, retrieve its name and voltage
for bus in busbars.values():
# do something with the bus
name = bus.GetName()
Two functions are also provided to return dictionaries of the unique component IDs. The dictionary keys are the Python script names while the dictionary values are the integer IDs.
Setting bFetchFromSystem to True forces IPSA to rebuild its internal component data maps. Setting bFetchFromSystem to False will only rebuild the internal component data maps if components have been added or deleted since the last Get… function call. If the script creates new data components during its execution then the internal component data maps will always be rebuilt and bFetchFromSystem can be True or False.
Component Ratings
Rating sets determine the thermal limits that branches and transformers can tolerate. Each component can be given a set of MVA or kA values which are checked after a load flow calculation to identify if the component is overloaded. In IPSA 1.x four rating sets were provided, namely Standard, Summer, Winter and Short. In IPSA 2 these rating sets are provided by default but users can add additional rating sets. The ratings sets defined by the user, either through the IPSA interface or via scripting, are stored with the network model.
The functions used to access the rating data have therefore been changed from IPSA 1.x in order to address the user-defined rating sets.
Profiles
Profiles represent a set of categories with associated MW and MVAr values. Profiles can be assigned to loads, synchronous machines and universal machines. Each network can have any number of profiles which can used to provide absolute or scaled MW and MVAr values. Every load, generator and universal machine in the network can be assigned one of the profiles and load flow analysis or profile analysis can then be performed. Scaling profiles cannot be assigned to universal machines.
Refer to section 0 for the function to run a profile study.
Different types of profiles are represented by different classes as follows;
Actual load profile class -
IscLoadProfilePQActualScaled load profile class -
IscLoadProfilePQScaleActual generator profile class -
IscGeneratorProfilePQActualScaled generator profile class -
IscGeneratorProfilePQScaleActual universal machine profile class -
IscUMachineProfilePQActual
Add Profile Categories
Profiles comprise a number of categories and associated MW and MVAr values. Each category is simply a string which identifies the category name. Examples of profile categories could be:
Spring, Summer, Autumn, Winter
Normal, Max Load, Min Load, Emergency
00:00hrs, 01:00hrs, 02:00hrs, 03:00hrs etc.
The category names are only for user interaction and do not relate to other network components or analysis settings such as equipment ratings.
Add Profile Data
Each profile category can be assigned a specific MW and MVAr load for the various profile types. The MW or MVAr value assigned to each category is either an actual value or a per unit scaling value depending on the profile type.
Add Profiles to Components
Once a profile has been created it can then be assigned to any number of individual loads, generators and universal machines in the network. The field index ProfileUID is set to assign a profile to a network load, generator or universal machine. This is detailed in the corresponding component sections and the code below illustrates the use of all the load profile functions.
# define the categories and loads
categories = {0:"00:00",
1:"06:00",
2:"12:00",
3:"18:00"}
mw = {0: 0.8,
1: 0.775,
2: 0.75,
3: 0.712}
mvar = {0: 0.48,
1: 0.465,
2: 0.45,
3: 0.4272}
# create a load profile
profileUID = ipsanetwork.CreateLoadProfilePQActual('Test Profile')
# get the profile ID
profile = ipsanetwork.GetLoadProfilePQActual(profileUID)
# add the categories to the profile and set the data
profile.SetCategoryNames(categories)
profile.SetPMW(mw)
profile.SetQMVAr(mvar)
# finally assign the profile to all network loads
loads = ipsa_network.GetLoads()
for load in loads.values():
load.SetIValue(ipsa.IscLoad.ProfileUID)
Running Profile Studies
All categories in the selected profiles are run and the results are obtained from the functions provided in each component class. All profiles must have the same set of category names. The load flow solution parameters are set using the IscAnalysisLF class.
