It is a standalone (Windows) application, but also cloud “Modeler Services” are available in a freemium model. Recently also free mobile application Ask ADONIS was added.Īcademic edition is also available with DMN, simulation and teaching materials.īizagi offers unique approach to process modelling. Apart from BPMN diagrams you can also create process architectures, organigrams and make a comprehensive documentation containing not only interlinked processes forming a process architecture but also references to roles (using RACI approach), applications, documents, KPIs, risks and much more.
Since several years ADONIS:CE is available for free in a cloud. Please note that while some tools mentioned below are simple diagramming tools, others are more advanced and allow you to do much more than create BPMN diagrams. However it is still possible to find standalone BPMN modelers – pretty commonly they are offered by vendors of the process automation/workflow software.
NAES performs all required studies to establish compliance.Since last post some things changed, so I prepared an update for you ?Īs in the last edition it is clearly visible that cloud tools are very popular. Entities are typically notified by the Planning Coordinator when an analysis is required. PRC-026 requires applicable entities to perform load responsive relay settings analyses based on criteria identified within the Standard. NAES utilizes predefined calculation options as well as simulations to determine a facility’s compliance status and development of new relay settings if required. PRC-025 establishes minimum settings requirements for load-responsive relays protecting generators, step up transformers, and auxiliary transformers.
NAES can complete protection settings analyses and provide compliance documentation that clearly identifies protection settings as they relate to NERC’s “no trip” zones.
PRC-024 requires applicable entities to ensure generator protective relays do not trip within predefined frequency and voltage limits.
NAES provides full engineering analyses to maintain compliance with this Standard. PRC-023 requires load responsive protective relays be set according to criteria within the Standard to ensure settings do not limit transmission loadability. NAES produces PRC-019 specific coordination studies for both traditional generators and renewable projects to establish compliance with the Standard. PRC-019 requires applicable entities to show coordination between voltage regulating controls, limiters, equipment capabilities, and protection settings. NAES can assist with the design and installation of DME as well as ongoing compliance support. PRC-002 requires the installation and operation of disturbance monitoring equipment (DME) for applicable entities. NAES offers both procedural documentation and engineering services to establish the required coordination for both PRC-001 and PRC-027. PRC-001 requires entities to coordinate protection system changes with other affected parties. You should allow time for at least one iteration with CAISO so that you are complete and deemed compliant before your deadline.ĬAISO Transmission Planning Website CLOSE Please contact NAES NERC Compliance Testing Services for additional information and support at wait until the last minute.
The following links will allow entities to determine when to expect their individual data requests (phase) and what data will be required (category). NAES is prepared to assist entities with data aggregation, modeling, and testing to ensure compliance with CAISO’s data requests. These models must be verified using criteria listed in the BPM, which can only be performed by entities with modeling software and knowledge of modeling practices. New data requirements include voltage and frequency protection models, power flow models, and in some cases, sub-synchronous resonance models. While additional requirements have been placed on larger NERC registered facilities, these changes may pose an even greater burden to entities that have been exempt from NERC mandated modeling and protection requirements.
Section 10 of the BPM establishes revised data requirements and compliance procedures for all participating generators including non-NERC registered entities.
On August 1, 2018, CAISO introduced a revised Business Practice Manual for Transmission Planning Process (BPM), which includes new data requirements for interconnected generation resources within the ISO’s footprint. Updated CAISO Generator Modeling Process and Data Requirements
