SEL Battery Engineer

Essential duties and responsibilities include, but are not limited to the following:

• Develop and implement Typhoon HIL simulation files and integrate HIL Connect modules with IO modules.

Maintain SEL735, SEL700G, and SEL3555 hardware devices that are connected to the HIL testbed. Also included will be to deploy TCP/Modbus or C37.112 PMU servers or clients that interface with production power plant controllers by implementation of emulators. Develop and maintain design, solution, and component specifications that are part of the HIL Lab to support controls logic testing and validation, either for new unit code implementations or production support issues.

• Assist in battery power plant (BPP) Commissioning operations efforts including power dispatch, troubleshooting discrete HW issues, and coordinating with Commissioning Leads.
• Review/coordinate design and other technical information from suppliers and contractors, including PSCAD studies and PPC control loop specification documents for transient studies.
• Perform other duties as assigned

To perform this job successfully, an individual must be able to perform each essential duty satisfactorily. The requirements listed below are representative of the knowledge, skill, and/or ability required. Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions. Knowledge

• Modeling of electrical power system equipment and source impedance, steady-state and transient power flow analysis.
• Creation of test plans and procedures to validate power plant controller hardware in loop testing.

Load type modeling and transient load variant flicker. Knowing how to analysis power quality issues such as Voltage flicker and harmonics, and work with inverter OEMs in how these can be resolved. Substation design and distribution automation transfer schemes. Digital Fault Recorders and PMU Channel streams with a Power System Dynamics understanding. EMS and SCADA implementation for utility-scale IBR systems or substations. Understanding on what digital signal processing (DSP) means the difference between analog and digital signals. Skills Typhoon HIL Simulation software center. RTDS simulation software center skills that are transferable to Typhoon. AcSELerator RTAC Programming in IEC 61131 PLC programming language. Supporting skills including Python 3.0, TCP network management, Fiber network technology such as RSTP. Controls protocols such as TCP/Modbus, C37.112, IEC61850, MQTT, P2P, TCP/DNP3.0. Data Collection methods and analysis to interpret simulation results and create reports and graphs for confirmation of successful runs. Basic hands-on electrical skills involved in physically deploying HIL simulation equipment or working on low voltage instrumentation & controls (I&C circuits (less than 24Vdc). Abilities Maintain the highest degree of honesty and integrity. Adaptable and keep a positive attitude when working under time pressure or shifting requirements. Protect confidential information by not communicating, disclosing to, or using it for benefit of 3rd parties. Intellectual Property protection of the EMS Platform is of utmost importance. Self-directed project management skills to lead initiatives to completion. Comply with all EHS policies, practices and procedures reporting all unsafe activities to Management and/or Human Resources. o Highly competitive, self-starter that can work both individually and in a group setting. Education & Experience Master’s or PhD degree in Electrical Engineering with a minimum of four (4) years of related experience in the field. Experience in deploying hardware-in-loop simulations that were integrated in testbeds for validating production ready control loops and logic. Experience with power systems transient simulations in at least one of the following technologies is a must: Typhoon HIL, RTDS, or PSCAD. Ideal if candidate has experience in working on or with Inverter-Based Resources (IBR) technology.
