Transmission System Analysis and Planning
PSS®E is the premier software tool used by electrical transmission participants world-wide. The probabilistic analyses and advanced dynamics modeling capabilities included in PSS®E provide transmission planning and operations engineers a broad range of methodologies for use in the design and operation of reliable networks. PSS®E is the standard Siemens offering for electrical transmission analysis that continues to be the technology of choice in an ever-growing market that exceeds 115 countries.
Since its introduction in 1976, the Power System Simulator for Engineering tool has become the most comprehensive, technically advanced, and widely used commercial program of its type. It is widely recognized as the most fully featured, time-tested and best performing commercial program available.
PSS®E is an integrated, interactive program for simulating, analyzing, and optimizing power system performance. It provides the user with the most advanced and proven methods in many technical areas, including:
- Power Flow
- Optimal Power Flow
- Balanced or Unbalanced Fault Analysis
- Dynamic Simulation
- Extended Term Dynamic Simulation
- Open Access and Pricing
- Transfer Limit Analysis
- Network Reduction
PSS®E Version 33 released May 2011.
At a glance
PSS®E high-performance transmission planning software has supported the power community with meticulous and comprehensive modeling capabilities for more than 40 years. Built on proven technology, Siemens PTI launches PSS®E Version 33 with new features and enhancements to improve your work flow, support grid code compliance and provide preventative security capabilities.
Overview
Version 33 introduces several new forms of analysis that includes Preventive Security Constrained OPF and N-1-1 contingency analysis. A number of new analytical models have been added along with the standardization of the Dynamic CONEC and CONET type models, improvements to data entry and connection codes in Short Circuit, an updated fully integrated Scenario Manager as well as improvements to basic power flow and dynamic simulation activities.
Native Induction Machine Model
As requested by the user community, Version 33 includes a native induction machine model which can be used for an accurate representation of induction motor type modes throughout the PSS®E engine.
Sensitivity Analysis
Sensitivity analysis is a method to systematically study the impacts of changes in system operation conditions such as MW and MVar power injections on changes in branch flows and bus voltages. The function can calculate sensitivity factors with either a DC linear network or full AC network and can be used in the following applications:
- Mitigate System Operating Limit (SOL) violations
- Determine loading contribution
- Increase transfer capability
- Develop cost allocation
Preventive Security Constrained OPF
System security is the ability of a system to withstand contingencies, in other words, to remain intact even after equipment outages or failures. The Security Constrained Optimal Power Flow (SCOPF) can be used to perform a secure control to ensure the system security. It is a special class of OPF problems which takes into consideration the system constraints of predefined contingencies. The preventive method enables the system to be prepared for certain contingencies beforehand, and it does not take into account the system’s post-contingency control capabilities.
N-1-1 Contingency Solution
The N-1-1 contingency solution performs an AC power flow to solve the primary contingency, applies the appropriate system adjustments in accordance with one of three adjustment modes, and then runs another AC power flow to solve the secondary contingency. The three modes are local control, corrective action and Preventive Security Constrained Optimal Power Flow (PSCOPF). Under each mode, several types of controls are available to adjust the system to meet the specified goals.
Dynamic CONEC and CONET model standardization
Provision has been made to call every PSS®E dynamic model from within PSS®E without the need for an explicit call statement in the connection routines (CONEC and CONET.) As a result of this change, no model in the PSS®E supplied library would require any compilation or linking of the connection routines. CCT models, a new family of models, have been introduced to replace the old CONEC and CONET type models. By using the new CCT models, in place of the old CONEC-CONET type models, users will be able to prevent user models from being called in the CONEC and CONET subroutines and thereby avoid compilation and linking of these routines.

PSS®E Xpress - More than just a viewer, an essential power flow toolbox!
In recent years, major blackouts around the world have increased awareness regarding the benefits of accurate modeling for improved system planning. Municipalities and cooperatives that have traditionally relied on regional independent system operators (ISO) or transmission owners (RTO) to provide planning modeling, need to be actively involved to ensure the accuracy of their own system representation. To streamline the process of exchanging data with their ISO, RTO, or other governing body, utility companies, municipalities and cooperatives need a solution to perform essential tasks in a cost-effective manner.
To address these challenges Siemens PTI offers PSS®E Xpress. Derived from our market-leading PSS®E transmission planning software and a 40-year heritage, PSS®E Xpress includes essential functions for modeling and data exchange.
