(Get-WmiObject win32_NTEventlogfile -Filter "LogFileName='System'").sources

$EventLog = New-Object System.Diagnostics.EventLog('System')
$EventLog.MachineName = "$env:computername"
$EventLog.Source = "It For Dummies"
$EventLog.WriteEntry("Event created by PowerShell, using a System.Diagostic.Eventlog object.",'Information',1234,2)
You’ll find a lot of details about that type of object here.
